Obelix is from a hydraulic equipment manufacturing company in Greece. At the beginning of last year, a hydraulic threaded cartridge valve that he purchased was complained by customer due to leakage. Obelix contacted the original manufacturer and the other party said that it must be a working condition problem that caused the seal to leak due to wear and tear, it can only be replaced. But 6 months later, the old problem occurred again. Obelix realized that the original manufacturer was unreliable and decided to find a new hydraulic threaded cartridge valve manufacturer. After sourcing for a week, no factory could guarantee zero leakage, making Obelix a big head.

 

Obelix found AAK hydraulic valves on Google and found that AAK has multiple cases of solving the leakage problem of hydraulic threaded cartridge valves. He left us a message: Can AAK achieve 100% leak free hydraulic threaded cartridge valves? AAK has received many such messages. I asked him to provide the production drawings and working conditions of the original hydraulic threaded cartridge valve. After analysis, AAK engineers found that the sealing structure of the original hydraulic threaded cartridge valve has potential hazards. If high-frequency operating conditions are encountered, the service life of the hydraulic threaded cartridge valve will be 6-8 months only. Obelix requested AAK to make samples. After 45 days, the samples were sent out.

 

Last week, Obelix sent us an email saying that it has been almost a year since using AAK hydraulic threaded cartridge valve with an improved structure. There has been no customer complaint due to leakage. His boss requested to replace all current valves with AAK hydraulic threaded cartridge valves. He needed AAK to ship 240 pcs as soon as possible.

 

AAK hydraulic threaded cartridge valve can achieve 100% leak free performance, due to 3 key points:

 

1.   The hydraulic threaded cartridge valve structure includes a cover plate of the pilot hole, a valve spool, a valve sleeve, a sealing ring, a guide rod, and a valve body. The cover plate and the valve body are connected by screws.

 

2.   The valve sleeve is inserted into the valve body, and there is a valve spool in the valve sleeve, and it is arranged under the cover plate. The bottom surface of the valve spool cavity is equipped with a return spring. The inner wall of the valve spool is equipped with a sealing ring that can prevent leakage from the pilot port, which can effectively prevent leakage from the pilot port.

 

3.   The main seal adopts a soft and hard composite seal structure with dual protection. The O-ring is installed on the valve spool guide cylinder, so that the O-ring can prevent oil from flowing back into the tank from the pilot hole.

 

AAK hydraulic threaded cartridge valve can not only prevent leakage at the pilot hole, but also prevent leakage of the main seal.

 

AAK hydraulic threaded cartridge valve, no leakage, you can also try a small one.
