  • Hydraulic Relief Valve Reduced Size With Smalley Wave Spring - China

    price: 100.00 Dollar US$

    AAK reduced the shape of the hydraulic relief valve by 35%, allowing the motor installed into the manifold, which can not be achieved by peers Jimmy is from a hydraulic equipment company in the United States.

    He has cooperated with AAK for more than 2 years and is very sticky about the quality of hydraulic relief valves.

    At the end of last year, the hydraulic pilot operated relief valve used in the hydraulic unit they developed could only be purchased from local manufacturer because of tight time.

    Problems were encountered in the hydraulic manifold installation.

    The existing hydraulic relief valve of the American factory occupied a little position of the motor, resulting in difficulties in the installation of the motor.

    If the position of the hydraulic relief valve is changed, the manifold oil circuit will be changed and the power supply of the hydraulic system will be affected.

    The manufacturer of the hydraulic pressure relief valve has no time to adjust the size.

    Jimmy had to look for other manufacturers of hydraulic pilot operated relief valves.

    After a week, he found more than 10 local manufacturers of hydraulic relief valves in the United States.

    Some of them were not willing to customize it due to small quantity, while some gave no reply at all.

    Jimmy was very helpless.

    Jimmy thought of AAK Hydraulic Valves in Ningbo and asked how long it would take to produce 10 non-standard hydraulic pilot operated relief valves? I felt his anxiety and asked if he had encountered any difficulties in purchasing hydraulic relief valves.

    Only then did he tell me the embarrassment he had encountered in domestic manufacturers in the United States.

    According to the drawings and manifold schematic diagram of the hydraulic pilot operated relief valve provided by him, AAK engineers also suggested that the hydraulic pilot operated relief valve should be redesigned to reduce the length of the hydraulic pressure relief valve by 35%.

    AAK can send 10 hydraulic pilot operated relief valves within 30 days.

    Their engineers doubted this innovation, because if the size is reduced by 35%, the load of the hydraulic pilot operated relief valve will be affected.

    We understood the concerns of their engineers.

    We would see the result in a month.

    If AAK hydraulic relief valve can not solve the problem of the manifold installation, we were willing to bear the loss.

    Jimmy was waiting for the sample of AAK with worry.

    After the samples were sent out, we soon received email from Jimmy.

    AAK newly designed hydraulic relief valve was successfully installed into the manifold, and the equipment commissioning was normal.

    Their engineers were satisfied.

    They were curious to know how AAK hydraulic pilot operated relief valve was reduced by 35% under the condition of ensuring parameter.

    AAK adjusted the size of the spring chamber of the hydraulic pilot operated relief valve, and used Smalley wave spring which has smaller size and can be put into the smaller spring chamber of the hydraulic relief valve.

    The wave spring adopts the winding process.

    It is a thin circular springy metal element composed of several wave crests and troughs along the circumferential direction in a sinusoidal form, can withstand large loads even with a small amount of deformation, and the force is symmetrical.

    Thus, the length of the hydraulic pilot operated relief valve can be shortened.

    AAK hydraulic pilot operated relief valve, has unique skills to solve the problem that American manufacturers can not do.
