Find Verified Hydraulic Counterbalance Valve Customized Design Suppliers, Manufacturers and Wholesalers

AAK customized hydraulic counterbalance valve replaced SUN, making Nancy win double the year-end bonus Nancy comes from a hydraulic equipment company in the United States. In October last year, they developed a hydraulic power unit that used a hydraulic counterbalance valve. Nancy purchased the standard parts of SUN hydraulics counterbalance valve according to the model required by the engineer. During the commissioning of the hydraulic power unit, the oil cylinder shook and made abnormal noise shortly after the equipment was started. After checking the design principle and installation method, the engineer judged that the problem probably lied in the hydraulic counterbalance valve. They asked to replace it with a new hydraulic counterbalance valve, but SUN after-sales personnel said that there would be no problem with the SUN hydraulic counterbalance valve and were unwilling to replace it. The engineer tested the hydraulic counterbalance valve separately, and the parameters were also normal. The technical team was confused. The promotion date of the new equipment was coming, but the machine test was stuck now, and the boss was also very anxious. Nancy tried to consult with different hydraulic counterbalance valve manufacturers, but after a week, there was no progress. She found AAK on Google and left a message to us: After using SUN hydraulic counterbalance valve, the equipment commissioning was abnormal, but no abnormality was found in the separate test of hydraulic counterbalance valve. At first glance, there seems to be no solution. Our engineer suggested Nancy to provide working condition requirements, hydraulic schematic diagram and equipment abnormal video. After discussion, AAK technical team judged that there was a problem with the flow selection of the hydraulic counterbalance valve. I told her that the flow difference of the cylinder diameter ratio of their power unit was 2.3 : 1. Although this ratio could be used for the standard parts of SUN hydraulic counterbalance valve, its stability was difficult to be guaranteed. This was the reason why the oil cylinder vibrated and made abnormal noise during the test run. Their engineers also recognized the reasoning of AAK technical team and asked AAK to customize standard two-way hydraulic counterbalance valves with appropriate flow. 45 days later, AAK sent 20 hydraulic counterbalance valves for test order. 2 weeks later, Nancy informed by email that the test run was successful with AAK hydraulic counterbalance valves, and the oil cylinder jitter and abnormal noise were disappeared, which could also catch up with the promotion of the equipment. Purchased a hydraulic counterbalance valve with unsuitable flow, no one in the company could solve the problem. It was solved by using AAK non-standard customized hydraulic counterbalance valves.

Zander is from a hydraulic manufacturing company in Greece. In the first half of this year, their company planned to upgrade the old logistics crane and put it back on the market. Its main goal is to improve its stability by 20% compared with its peers. The optimization of the hydraulic cartridge counterbalance valve is the key, but the original hydraulic cartridge counterbalance valve manufacturer has no ability to innovate. Zander found a local hydraulic cartridge valve manufacturer to optimize the structure and make samples. However, during commissioning, when the load of the system drops, the pressure fluctuation cannot exceed that of the peers, and the hydraulic cartridge counterbalance valve cannot avoid load interference. The local hydraulic cartridge valve manufacturer has no ability for further improvement. 2 months passed by, but there was still no solution. The boss pushed for progress many times, and Zander was worried. Zander found AAK on Google, noticed that AAK had released some customer cases about hydraulic cartridge counterbalance valves, and sent us an email. According to the schematic diagram of the hydraulic system and the original hydraulic cartridge counterbalance valve drawing provided by him, AAK engineer informed that the structure optimized by his local hydraulic cartridge valve manufacturer was not reasonable and needed to be adjusted. AAK has a trick to prevent the hydraulic cartridge counterbalance valve from being affected by the load. Zander asked for AAK samples. After 45 days, AAK sent 20 samples of hydraulic cartridge counterbalance valves. 3 months later, Zander sent an order for 500 hydraulic cartridge counterbalance valves, and told us that their technical department was very satisfied with AAK hydraulic cartridge counterbalance valves. Not only did they overcome the load impact, but also improved the stability of their new logistics crane by more than 20%. In the promotion stage, the booking was good, and the boss was happy. AAK hydraulic cartridge counterbalance valve can stably control the opening of the valve spool without being disturbed by the load, and its stability is higher than that of its peers, because we have tricks on optimizing the structure. AAK hydraulic cartridge counterbalance valve is composed of a valve body, a valve seat, a main valve spool, a pilot valve spool and a pilot mechanism. The valve seat is connected with the valve body and forms a connected first channel. The extended end of the valve seat butts against the pilot mechanism and forms a second channel. The main valve spool is provided with a throttling slot. One end of the pilot valve spool slides and is arranged in the inner cavity of the main valve spool. The other end is connected with the pilot mechanism. The pilot valve spool is equipped with a throttling slot. The pilot valve spool is connected with the inner cavity of the main valve spool as a balanced structure.

AAK 3 Skills Solved the problem of Hydraulic Counterbalance Cartridge Valve Caused by Back Pressure and helped Dorian's Equipment to be Promoted Smoothly Dorian is from a Greek hydraulic equipment company and is responsible for the procurement of hydraulic components. At the beginning of the year, they developed a new hydraulic crane, which requires the use of hydraulic counterbalance cartridge valve. Dorian worked with a local manufacturer to make samples. During the equipment commissioning, it was found that the hydraulic counterbalance cartridge valve had no overflow function due to the back pressure. The hydraulic system was tested separately, but it was normal. Dorian felt that there was a hidden danger in the original design of the hydraulic counterbalance cartridge valve. The engineer thought that the function of the hydraulic counterbalance cartridge valve was not up to standard. Dorian was a little embarrassed. Dorian found website of AAK hydraulic valves on Google, and noticed that AAK had been supplying first-line brand hydraulic valves such as HydraForce, SUN Hydraulics, and HAWE for many years. Maybe he saw hope and sent an email to ask for help. According to what he said, the hydraulic counterbalance cartridge valve has no overflow function under the influence of the back pressure of the closed central circuit. I told him that it was probably a flaw in the design of the original hydraulic counterbalance cartridge valve. According to his hydraulic schematic diagram and original drawing of hydraulic counterbalance cartridge valve, AAK engineer not only determined that the problem was in the original design, but also had a solution. After knowing these, Dorian asked AAK to make samples. After 50 days, AAK sent 10 hydraulic counterbalance cartridge valve samples. 4 weeks after AAK hydraulic counterbalance cartridge valve samples were sent, Dorian told me that the equipment debugging was smooth and the market promotion had been started. I was asked to wait patiently for the batch order. The rapidity and stability of AAK optimized hydraulic counterbalance cartridge valve is the key to smooth equipment commissioning. It solves the contradiction between the rapid response and stability of the equipment in the early stage, and the flow change is moderate, the movement is stable, the safety overflow function is not affected by the back pressure, which can be applied to the closed center and open center hydraulic systems. 1. The middle section of the hydraulic counterbalance cartridge valve spool is provided with an inner concave ring, which is also the valve inlet. The right end of the inner concave ring has a cone, on which there is a two-stage stepped taper ring. The cumulative area of the cone is the same as the area of the cylinder end face at the right end of the counterbalance cartridge valve spool.

For Hydraulic Counterbalance Valve benchmarking HAWE, it is difficult for AAK to find rivals in the field of high pressure resistance Santiago is from Spain. He has been a purchaser of the company for 3 years. His boss trusts him very much. Unexpectedly, a hydraulic counterbalance valve overturned him. In the second half of last year, one of their hydraulic cylinders was complained by the customer because of shaking. The engineer judged that the hydraulic counterbalance valve used was abnormal, but the reason was unknown. After receiving the defective hydraulic counterbalance valve, the original manufacturer found that the internal pressure spring had failed, resulting in the slow response of the hydraulic counterbalance valve. This is the best pressure spring of the original manufacturer, but it still could not withstand the impact of 450bar high pressure and high frequency. Santiago had to change the manufacturer of the hydraulic counterbalance valve. After more than a week, no manufacturer was able to guarantee that the valve would not fail under the high pressure of 450bar for more than 1 year. It had been nearly 2 weeks, and there was no solution to customer complaints. Santiago was under great pressure. Santiago accidentally found AAK Hydraulic Valve in Google. He left a message on the AAK website asking whether the pressure spring of the hydraulic counterbalance valve would not fail for more than 1 year under the high pressure and high frequency working condition of 450bar? According to his drawings and working conditions, I told him that if the German HAWE was used, it would be 100% OK, but the quantity was too small, and HAWE would not necessarily accept it, and the cost was not low. AAK has a similar hydraulic counterbalance valve. Let's see if it can be a substitute first? 3 weeks later, Santiago informed that the AAK hydraulic counterbalance valve could be installed with their hydraulic cylinder and operated normally. But he seemed worried that it would not last long. I told him that Germany HAWE is the first brand of hydraulic valves in the subdivision field of high pressure resistance. The function of AAK hydraulic counterbalance valve benchmarks HAWE, which has been shipped for many times. The fact has proved that there is no repair report for 1 year, and the pressure spring can not lose efficacy for more than 1 year. Why dare I say so? The pressure spring of AAK hydraulic counterbalance valve is made of 60Si2CrVA alloy steel. At the same time, in combination with special heat treatment process, 60Si2CrVA pressure spring steel is heated to 860 �° c, kept for 20-40 min for austenitizing, and then subjected to short-term high-temperature water cooling quenching to room temperature. The comprehensive properties of the treated 60Si2CrVA spring steel have been improved by at least 2 times, especially the strength and toughness of the pressure spring, which quality far exceeds most springs.

The 1 million times durability of hydraulic counterbalance valves, AAK quality benchmarked with SUN hydraulics, but the price was 30% cheaper Last week, the German customer Thorsten sent an order for 1,200 hydraulic counterbalance valves, and said that only AAK and SUN hydraulic counterbalance valves passed 1 million durability tests among the 6 hydraulic valve manufacturers making the samples. However, the price of AAK was 30% lower than that of SUN, and the delivery time was faster. In May this year, Thorsten's company received an order for a batch of special hydraulic winches. The customer requested that the equipment be guaranteed for at least 1 year of service life. The engineer required that the durability test of the hydraulic counterbalance valve to be purchased by Thorsten must reach more than 1 million times. Thorsten found a local hydraulic counterbalance valve manufacturer to carry out the test. After 100,000 times, the O-ring wear affected the seal. After the sealing ring was replaced, the valve spool and valve body were worn and leaked again after 200,000 times, and the local manufacturer surrendered. Thorsten had to find a manufacturer of hydraulic counterbalance valves with higher durability. In order to avoid wasting purchasing time again, the two schemes were carried out simultaneously. One is to purchase the original SUN hydraulic counterbalance valves, and the other is to find a factory for customized hydraulic cartridge valves. When Thorsten contacted AAK, I told him that the requirement of hydraulic counterbalance valves for 1 million times was not very high. How could local hydraulic valve manufacturer fail? Thorsten said that when testing this hydraulic counterbalance valve, the opening and closing cycle time is set to 5 seconds, the set pressure is 21 PMa, and the flow rate is 9L/min. The wear resistance of the sealing ring, valve spool and valve body is at least 50% higher than that of the conventional hydraulic counterbalance valves. This time, including AAK, there are 6 hydraulic valve manufacturers to make samples. More than a month later, Thorsten said that among the 6 hydraulic counterbalance valve manufacturers, only AAK and SUN hydraulic counterbalance valves have passed the durability test for 1 million times, but the price of AAK is 30% lower than that of SUN. At the same time, AAK can provide a delivery time 4 weeks faster than that of sun. Thorsten especially wants to know why AAK is so strong. AAK hydraulic counterbalance valves are different from peers due to the following 3 points: 1. AAK adopts Japanese special polyurethane rubber sealing ring for this hydraulic counterbalance valve. Under the special working condition required by Thorsten, the durability limit of rubber sealing ring is about 100,000 times only, while the wear-resistant and high-pressure resistance performance of ours is more than twice that of other rubber sealing rings.

Bill is a purchaser of Manitowoc company in the United States. Two years ago, AAK received an inquiry about hydraulic counterbalance valves from him, and there were few contacts later. Unexpectedly, two years later, we received an email from him consulting about the problems of the hydraulic counterbalance valves. After communication, we learned that a batch of hydraulic counterbalance valves he purchased elsewhere had problems and almost got into a big trouble. Last summer, a crane shipped by their company, the crane winch system lost control during construction and the hook slipped off. Fortunately, there was no one under the hook at that time, otherwise there would be great trouble. According to the analysis of the field engineer, it is considered that the hydraulic counterbalance valve used in the crane winch system is abnormal. After disassembling the hydraulic counterbalance valve, it is found that there is a deviation in the concentricity between the valve spool and the valve seat. The valve spool is affected by large eccentric hydraulic force, so that the hydraulic counterbalance valve lost its function of balance and the hook slipped off. After knowing the reason, Bill contacted the original hydraulic counterbalance valve supplier. The supplier replied that the hydraulic counterbalance valves were indeed within the warranty period, he can replace the abnormal hydraulic counterbalance valves with a new ones, but can not guarantee that each hydraulic counterbalance valve had the same concentricity and could be used for more than 1 year. Bill was worried about the stability of the new hydraulic counterbalance valves. He didn't want to have big trouble and had to find a new hydraulic counterbalance valve manufacturer. In crane hydraulic system, the performance of hydraulic counterbalance valve is the cornerstone of winch system, and the consistency of hydraulic counterbalance valve concentricity is the key. Bill also asked other hydraulic counterbalance valve manufacturers. No factory guarantees that the concentricity of the hydraulic counterbalance valve can be still consistent after 1 year of use. Bill wants to know how about the concentricity of AAK hydraulic counterbalance valves after being used for 1 year. We told Bill that perhaps having a try is the best answer. He can detect the concentricity of AAK hydraulic counterbalance valves in an all-round way. After 15 days, we sent 4 samples of hydraulic counterbalance valves according to his drawings. Seven days later, Bill informed us that the concentricity test data of AAK hydraulic counterbalance valves were indeed more comprehensive than that of his original manufacturer. How to ensure that the concentricity of AAK hydraulic counterbalance valves is still consistent after 1 year of use? For some manufacturers, when processing the components of hydraulic counterbalance valves, there are discrepancies between the specification parameters and design,
