Shandong Senteke Hydraulic Co.,Ltd.We are manufacturer of cartridge valve and hydraulic system.And we can design valves according to your requirements

In Ningbo, the hometown of hydraulic valves, conservatively speaking, there are more than 100 hydraulic cartridge valve manufacturers. 4 years ago, we began to contact HydraForce. AAK HYDRALUC VALVE lasted 2 years, replaced hydraulic valve materials 3 times and proofed 4 times, becoming the first hydraulic cartridge valve manufacturer supplier of HydraForce valves among so many hydraulic cartridge valve manufacturers in Ningbo. 4 years ago, I received a call from President Li, who is the agent of HydraForce valves in China. He said that from the hydraulic cartridge valve manufacturers in Ningbo, he heard that AAK HYDRAULIC VALVE have invested a lot of equipment and constantly innovated technology, and has a good benchmark in Ningbo among hydraulic cartridge valve manufacturers and asked if we are not interested in becoming a supplier of HydraForce valves. Everyone wants to cooperate with top 500 enterprises in the world. While agreeing, I am also a little nervous. I am worried that if the quality of hydraulic valves does not meet the standard, we would make jokes among these hydraulic cartridge valve manufacturers in Ningbo. The first entry point between us and hydraforce valves is a hydraulic cartridge valve. The AAK HYDRAULIC VALVE technical team spent 33 days and sent the approval sample of the hydraulic cartridge valve. We soon got a reply from HydraForce valves. They asked us to re-make sample, listed us those parameters to be improved, and also gave us some encouragement. At present, AAK HYDRAULIC VALVE parameters are among the top 3 of the hydraulic cartridge valve manufacturers in Ningbo. Since AAK HYDAULIC VALVE can represent the manufacturer of hydraulic cartridge valve in Ningbo, we must continue to overcome difficulties until the sample of hydraulic cartridge valve is approved. We constantly tested imported materials, replaced imported machine tools with higher precision, designed different fixtures, and assembled special equipment required for proofing. The 4th hydraulic cartridge valve has finally been recognized by HydraForce valves, and has also been affirmed by hydraulic cartridge valve manufacturers in Ningbo. AAK HYDRAULIC VALVE, in 2 years, replaced hydraulic valve materials 3 times and proofed 4 times, became the first hydraulic cartridge valve supplier of HydraForce valves among so many hydraulic cartridge valve manufacturers in Ningbo.

AAK Hydraulic Cartridge Relief Valve, helped Monroe promoted to purchase manager Monroe is from Turkey, and has cooperated with AAK for 3 years. He purchases cartridge valves equivalent to HydraForce standard parts 3-5 times a year. Some time ago, he emailed me to ask: Can you customize non-standard parts of hydraulic cartridge relief valve? I was a little surprised because there was no inquiry for non-standard cartridge valves in the past 3 years. After communication, it was learned that the hydraulic cartridge relief valve used in one of their hydraulic cylinders encountered a problem. The vibration of the oil cylinder was severe, and the problem came from the hydraulic cartridge relief valve, which was slow in response to overload and overflow. This cartridge relief valve was customized from a hydraulic cartridge valve manufacturer in Ningbo. The manufacturer had optimized it twice, but the improvement was not obvious. I asked him if as long as the hydraulic cartridge relief valve is sensitive to overload and overflow, it can solve the problem of cylinder jitter. I was just afraid to waste his sample time. After getting the approval of their engineer, according to his system schematic diagram and the original drawing of the hydraulic cartridge relief valve, AAK engineer judged that after change the pilot function of the original hydraulic cartridge relief valve, it can react sensitively. After 35 days, AAK sent 8 samples of hydraulic cartridge relief valves. During the CNY, he sent us a PO of 280 hydraulic cartridge relief valves. He said that the cylinder fitted with AAK hydraulic cartridge relief valve very well, and did not shake. The customer was very satisfied with the trial of the cylinder, and placed the order with them for the cylinder. AAK hydraulic cartridge relief valve is sensitive to overload and overflow. The key is that we have made 3 breakthroughs in valve spool, seat structure and sealing. The optimized AAK hydraulic cartridge relief valve strengthens the pilot function, and can directly push the valve spool to release pressure without opening the pilot structure first. In the overload of hydraulic cartridge relief valve, the overflow action is more direct and sensitive. 1. Change the through-hole of the oil replenishing valve spool of the hydraulic cartridge relief valve to be larger than the cross-sectional area of the valve seat opening, and the oil replenishing valve spool and the overflow valve spool are arranged coaxially, and the pressure regulating screw is connected with the pressure regulating lock nut through the thread. 2. One end of the oil inlet of the valve seat is connected with the rear through-hole of the oil filling valve spool, and is equipped with a sealing ring and a spring. 3. The left end of the valve seat is the clamping part, the middle and front parts are the plug-in parts which are similar to the cylinder structure,

3 Highlights of AAK Hydraulic Cartridge Counterbalance Valve, Camden gave up SUN Camden is from a hydraulic equipment company in Sweden and has been engaged in procurement for 2 years. One of their customers ordered 2 sets of customized hydraulic power units, and specially reminded that the working environment of the equipment is 20 â?? below zero. The hydraulic power unit is required to be durable for at least 1 year, and its stability should be the first. Their engineer suggested purchasing SUN hydraulic cartridge counterbalance valves, but the parameters of SUN standard parts could not fully meet the requirements of equipment working conditions, and there is no enough quantity and time to customize SUN hydraulic cartridge counterbalance valves. Camden contacted a local manufacturer of hydraulic cartridge counterbalance valves, and the manufacturer was willing and confident to sample. 3 months later, the customer complained that the equipment was not stable enough, but it was barely usable. 6 months later, the equipment went on strike. During after sales service checking, it was found that the control of the hydraulic cartridge counterbalance valve was abnormal. The original manufacturer was surprised and confused. After disassembling the hydraulic cartridge counterbalance valve, it was found that the installation torque was too large, which could easily cause the valve to jam, and there were also abnormal seals, the original manufacturer had to surrender. Camden tried to find a new manufacturer of hydraulic cartridge counterbalance valve. After a week, it was fruitless. The boss blamed Camden for poor procurement. Camden noticed AAK at Google and found that AAK Hydraulic Valve is SUN's supplier of hydraulic components for 5 consecutive years. He left a message: SUN is unwilling to sample a hydraulic cartridge counterbalance valve, and AAK is able to do a good job? The hydraulic cartridge counterbalance valve shall be durable for not less than 1 year, and its stability shall be guaranteed. I have judged that he is in trouble when purchasing hydraulic cartridge counterbalance valves. According to the hydraulic schematic diagram of the system, hydraulic cartridge counterbalance valve drawings, equipment working condition parameters and working scenarios provided by Camden, AAK engineer found that this hydraulic cartridge counterbalance valve is similar to the hydraulic cartridge relief valves that we supplied to a Russian customer 1 year ago, which had a service life of at least 1 year under extremely cold conditions of - 55 â??. Camden was very happy to learn about the similar customer case of AAK, and requested to customize the hydraulic cartridge counterbalance valve and benchmark SUN. I said that AAK does not pursue whether this hydraulic cartridge counterbalance valve is advanced, but it must benchmark SUN in stability and reliability. At the same time, AAK needs to redesign this hydraulic cartridge counterbalance valve from 3 aspects.

The Hydraulic Cartridge Needle valve that HydraForce can't make, AAK has done it in 30 days Rogelio is from Spain and we met 1 year ago. He sent inquiries about hydraulic cartridge valves to AAK for several times. Some time ago, he came to me and asked for help to make a batch of hydraulic cartridge needle valves. The hydraulic cartridge needle valve used on the hydraulic cold drawing machine they sold to Vietnam has expired the warranty period and needs to be replaced. This hydraulic cartridge needle valve is purchased from HydraForce, and it is not a standard part. HydraForce said that this valve was produced 2 years ago, it is out of stock now and will take 3-4 months to produce it. But the customer was not satisfied with this time frame and complained to his boss. In order to catch time, Rogelio contacted more than 10 Chinese manufacturers of hydraulic cartridge needle valves. They either could not benchmark with HydraForce, or they could not meet the time, so Rogelio was anxious. Rogelio remembered that AAK had supplied HydraForce for 9 consecutive years. He believed that I can help him. According to the hydraulic cartridge needle valve drawings provided by Rogelio, the production time is only 30 days. I told him that the lead time was only 30 days, and the manufacturing quality of hydraulic cartridge needle valve was up to the standard of HydraForce, few Chinese hydraulic valve manufacturers could meet these requirements. Rogelio thought that I was ready to give up, he was willing to give AAK 40 days and paid for 100 hydraulic cartridge needle valves the next day. 30 days later, AAK sent 100 hydraulic cartridge needle valves to their Vietnam factory. Rogelio informed by email last week that it was out of his expectation that AAK still completed the production in 30 days. Their customer was very satisfied with their replacement of the hydraulic cartridge needle valves. Rogelio also specifically mentioned that he had asked more than 10 hydraulic cartridge needle valve manufacturers, their lead time was at least 50 days and can not 100% guarantee to benchmark the manufacturing quality of HydraForce. AAK was the only one that could catch up with the delivery date and also benchmarked the manufacturing quality of HydraForce. For this non-standard hydraulic cartridge needle valve, AAK has 3 advantages, which are beyond the reach of most hydraulic cartridge valve manufacturers: 1.AAK adopts Japanese OKK ultra precision machine tool, and the machining accuracy of components can reach 0.01~0.3�¼m. The precision of shape and contour is 0.003 - 0.1�¼m. Its production efficiency is 30% higher, which is the cornerstone of AAK's ability to catch up the delivery. 2. AAK has been hydraulic cartridge valve ODM manufacturer of 3 world top 500 companies for 10 years. Its quality control process is more strict than the ISO certification system. We have been focusing on details and constantly optimizing technology.

The hydraulic cartridge directional control valve that HydraForce can't make, is customized by AAK for navigation Fossette is from a navigation and aerospace equipment company in Canada, and has been purchasing for 4 years. At the beginning of the year, their customer wanted to customize a marine hydraulic power unit, which was very strict with the hydraulic cartridge directional control valve. He contacted HydraForce for customization. Because of small quantity and tight time, HydraForce could not meet the needs of Fossette. He selected hydraulic cartridge directional control valve manufacturer in Ningbo, who has cooperated for 2 years, to make samples. The manufacturer guaranteed that the geometric accuracy of the valve spool and valve cage is 0.8�¼m, but it was jammed during equipment commissioning. The hydraulic cartridge directional control valve of this manufacturer is inflexible, and the accuracy is 50% lower than the requirement. At this moment, the manufacturer said that 1.2�¼m of hydraulic cartridge directional control valve is the limit, and their engineers can't fulfill their promises. Fossette contacted more than 10 manufacturers of hydraulic cartridge directional control valves, but it was also fruitless. The time was wasted for 6 weeks, the customer was dissatisfied, and Fossette started to worry. Fossette saw on B2B that AAK has released a customer case about "0.8�¼m Accuracy of hydraulic directional control valve", he left a message on AAK Hydraulic Valve website, asking 3 questions consecutively: 1. Accuracy 0.8 �¼m Hydraulic cartridge directional control valve, are you SURE? 2. Customization time? 3. The quantity is small, are you interested? He specially emphasized â??SUREâ?? in capital letters. He may be feared of being disappointed again. I told him that the precision of 0.8�¼m Hydraulic cartridge directional control valve, is already an existing fact for AAK, it is not a matter of SURE or not. I need a complete drawing to evaluate the probability of customization success as a whole. 40 days later, AAK sent 10 customized hydraulic cartridge directional control valves. After that, there was no email from Fossette, and I did not follow it. Generally, the customer will give a feedback 2-4 weeks after receiving the samples. 4 months later, just last week, Fossette informed us that his customer was very satisfied with the marine hydraulic power unit they provided. He was preparing for the annual order and asked me to keep an eye on the production in the workshop to ensure the progress and manufacturing quality of large goods. The hydraulic cartridge directional control valve accuracy within 0.8�¼m, challenges the processing equipment, the technical team and the manufacturer's quality awareness. 1. In terms of finish machining, OKK ultra precision machine tool from Japan is used, and AAK self modified fixture is equipped, accuracy of 0.8 m is not our limit.

Hydraulic Cartridge Directional Control Valve with high-precision valve hole, AAK helped Santiago win big order The cylindricity of the valve hole of the hydraulic cartridge directional control valve is 0.002mm, and the roughness is Ra0.05. The supplier who has cooperated for 3 years gave up 2 weeks after receiving the order. After AAK took over, the precision of the hydraulic cartridge directional control valve was constantly challenged from 3 aspects. After processing, the cylindricity was less than 0.001 mm, the roughness was Ra 0.04, and the consistency of component dimensions was within 0.001 mm. 3 months later, Santiago gave AAK an order for 1000 hydraulic cartridge directional control valves. Santiago is from a hydraulic equipment manufacturing company in Brazil. In January this year, their company needed a batch of hydraulic power units with high requirements, which also had high requirements for hydraulic cartridge directional control valves, especially the valve hole cylindricity below 0.002mm and roughness Ra0.05. Santiago chose a hydraulic cartridge valve manufacturer who had cooperated for 3 years to make samples. 2 weeks later, the manufacturer gave up due to not able to meet the valve hole high accuracy of the hydraulic cartridge directional control valve. Santiago found AAK on Google and needed our help to sample it. After communication, we learned that the original manufacturer was not helpful. I told him that for hydraulic cartridge valves with similar accuracy, we had customized them and also supplied them to Brazilian customers. Santiago seemed to see hope and sent a test order for 20 hydraulic cartridge directional control valves. After 40 days, AAK delivered samples. After receiving the samples, Santiago just advised us that the sample accuracy met the requirements, and there was no further news. 3 months later, Santiago suddenly sent us an order for 1000 hydraulic cartridge directional control valves, and advised us that their customer was very satisfied with their hydraulic power units. They successfully received a large order from customer. They also stressed the importance of large goods, and should ensure that there is no deviation in accuracy. AAK's machining of hydraulic cartridge directional control valve holes with high precision requirements mainly comes from 3 points. Once determined, there is no deviation. 1. In the rough machining process, the high-precision machine tool in Japan and the high-pressure internal cold drilling U-drill are used. The range of valve hole diameter can be 13.5mm, and the hole straightness can be within 0.02mm. General hydraulic cartridge valve manufacturers do not have this kind of drill. 2. In the high-precision valve hole honing, the fixed size honing is adopted, which does not expand or shrink during processing, and the size allowance can be gradually removed in order.

has purchased hydraulic valves from for 6 years, and has cooperated with in several non-standard hydraulic cartridge valves. Some time ago, some customers complained that their logistics transmission equipment was not easy to operate. After the after-sales inspection, it was found that the hydraulic cartridge relief valve on the rotary device failed to buffer and the pressure regulation was not smooth. The original manufacturer said that this hydraulic cartridge relief valve was benchmarked to the standard parts of HydraForce, and he was unable to optimize. contacted me and asked me how to make the hydraulic cartridge relief valve easy to adjust pressure and have buffering function. According to the hydraulic schematic diagram and the original hydraulic cartridge relief valve drawing provided, engineer found that the requirements can be met as long as the original structure is improved. After 35 days, sent 20 samples of hydraulic cartridge relief valves. Last week, Clinton sent a PO for 200 hydraulic cartridge relief valves. He said that when hydraulic cartridge relief valve was installed, the customer no longer complained. It not only provided convenient pressure regulation and effective buffering, but also improved the stability of the equipment. They planned to replace the whole batch of equipment with hydraulic cartridge relief valves. hydraulic cartridge relief valve, the spool, buffer piston and pressure regulating valve housing cooperate to achieve buffer overflow effect, and the overall performance is reliable and stable, mainly from 3 unique structures: 1. The valve housing is provided with a first oil port, and the valve seat is provided with a second oil port. The valve spool can move axially, and the front end cooperates with the rear port of the valve seat to control the on-off between the second oil port and the first oil port. The channel port in the front end of the valve spool is provided with a plug, and the plug is axially provided with a damping hole. The front end face of the valve spool is equipped with a filter screen, and the front pressure surface of the valve spool is larger than the rear pressure surface. 2. The inner cavity of the front end of the pressure regulating screw nut has a buffer piston, and the rear end has a guide part. The radial bulge in the middle forms a convex ring part. The axial opening in the front end matches with the rear end of the valve spool. The oil supply in the middle of the convex ring part is with the connecting channel outside the rear end. 3. The pressure regulating screw is hollow at the rear end of the valve spool to form an inner cavity, which can move axially and change the axial force of the spring. The inner cavity wall of the front end of the pressure regulating screw is matched with the front end face of the convex ring to limit the buffer piston to move forward.

Buy hydraulic cartridge check valve samples 3 times a year, and hit AAK with a big order for the fourth time 1 year ago, Ferdinand from Germany left a message on AAK Hydraulic Valve website: Is there a hydraulic cartridge check valve equivalent to HydraForce? Ferdinan bought two hydraulic cartridge check valve samples from the model number I provided, then there was no news. Three months later, he bought another two samples of hydraulic cartridge check valves equivalent to SUN. Six months later, he sent a customized hydraulic cartridge check valve drawing and brought 6 samples, there was no email for 6 months. I think it's a bit abnormal, but if something is abnormal, there must be evil. He bought hydraulic cartridge check valve samples from AAK 3 times a year to test my patience and inspect the manufacturing quality of AAK. I can only comfort myself in this way. Last month, Ferdinand sent an email asking about the lead time for 1,200 pcs of hydraulic cartridge check valve customized last time. I knew that AAK had passed the investigation period of German customers. After communication, I learned that the hydraulic cartridge check valves that he purchased in Ningbo 2 years ago, were tested with 6 hydraulic valve manufacturers before and after. Either the first sample was OK, but the second one was not up to standard; Either the existing valve was tested OK, but the customized valve was abnormal. Time was wasted and delayed their equipment development. It turns out that Ferdinand was feared by some hydraulic valve manufacturers, so he was prudent to select new hydraulic valve manufacturers. This time, they will develop a hydraulic boarding bridge, which requires non-standard hydraulic cartridge check valves. From trial order to large order, AAK has been investigated for more than 1 year. Ferdinand said that the manufacturing quality of AAK hydraulic valves, whether the ones benchmarking international brands or non-standard customized ones, had been recognized by their engineers for their functions and performance, so they decided to place large quantity order of hydraulic cartridge check valves. The reason why AAK hydraulic cartridge check valve is different from other hydraulic valve manufacturers in Ningbo is that we insist on the quality of manufacturing. 1. Not make do with the equipment. No matter CNC machining center or machine tool, only high-precision ones are selected. At the same time, the fixture is upgraded and modified by ourselves, eliminating human error. 2. Materials should be paid attention to. Different kinds of imported high carburized bearing steel should be combined with AAK's proprietary heat treatment process. The hardness of the material has gone up several steps, and its wear resistance has been improved by more than 3 times. The thermal stability and compressive strength of materials have been far ahead of other hydraulic valve manufacturers.
