This valve is widely used in the pipe system such as venting and environment protection in building material, glass, mining, power, light industry and papermaking departments. It can change the flow and cut off gas medium in the pipe by the different control signal. The valve has the features of lightweight, compact structure, endurance, little in the lost of flow resistance, high working pressure, flexible operation, definite direction, easy to maintenance and long life. It can be installed at any angle. It is suitable in the condition of adjusting, cutting off and self-protecting quickly. The valve is used with DKJ, ZKJ, Bernard electric actuator and other accessory to form a complete set to realize manual and automatic exchange without interference, micro-computer long-range control, automatic control or center concentrating control. It is the ideal equipment of realizing operation of automatic control and adjusting flow.

Fasteners are the general term of the class of mechanical parts used in fastening two or more parts (or components) into a whole. It is widely used in energy, electronics, electrical appliances, machinery, chemical, metallurgy, mold, hydraulic and other industries, at the same time, in various kinds of machinery, equipment, vehicles, ships, railway, bridge, construction, structure, tools, instruments, chemical, instruments and supplies, you can see all kinds of fasteners, is the most widely used mechanical foundation parts. It is characterized by a wide variety of variety specifications, different performance uses, and a very high degree of standardization, series, and generalization. Therefore, a class of fasteners that already have national standards is called standard fasteners, or simply standard ones.

AAK hydraulic pressure control valve has a performance of 2 million times, Davis will not change the supplier any more
Davis comes from a hydraulic equipment company in the United States. He has cooperated with AAK for 4 years, and it is very smooth. It is strange that since an inquiry of hydraulic pressure control valves in the second half of last year, there has been no new inquiry from him, only the reorders of some hydraulic cartridge valves. At the beginning of August, Davis asked about the production time of 200 hydraulic pressure control valves, and only then did we know that why he did not place orders for new valves for a long time. In the second half of last year, he found a hydraulic valve manufacturer whose price was more than 20% cheaper than that of AAK, so he moved the business to that manufacturer. But now troubles come out one after another, the boss is very dissatisfied, and he is under great pressure.
The most troublesome thing is that a three grip electro-hydraulic puller is weak in grasping due to the leakage of the hydraulic pressure control valve. However, the manufacturer of the original hydraulic pressure control valves prevaricated, and the high frequency of use of the equipment caused the wear of the valve body, and even refused to replace the goods. Davis regretted his decision. He caused big trouble for the first time because of the 20% price difference, and had to get back to AAK. In the past 4 years of cooperation with AAK, there was no complaint. In order to help Davis get out of the predicament as soon as possible, we adjusted the production arrangement of the workshop. 2 weeks later, 200 hydraulic pressure control valves were delivered. Davis also sent me the drawings of other valves produced by that manufacturer with lower price, and asked me to be prepared for production.
AAK hydraulic pressure control valve is wear-resistant and leak free, ahead of most hydraulic valve manufacturers in 3 aspects, which are also the important points to ensure the performance of 2 million times.
1. In terms of materials, AAK adopts German 20CrNi2MoV high carburized bearing steel. Through secondary quenching + cryogenic treatment + low temperature tempering process, its microhardness is 237 ~ 247HV, and its wear resistance is 3 times higher than that of similar steels. Most hydraulic valve manufacturers may know how to choose materials, but they may not do a good heat treatment.
2. On the equipment, AAK uses the Japanese NP520X-F full-automatic grinder to finish the valve spool. The surface of the processed valve spool is like a mirror with an accuracy of 0.8�¼m, the flexibility of the valve spool is improved by at least 2 times. Most hydraulic pressure control valve manufacturers can not process the same quality valve spool as AAK.
