AAK Hydraulic Cartridge Valve 1 Million times Service Life Control

Cannan is from Israel. Recently, they developed a hydraulic unit, which requires high-precision hydraulic screw-in cartridge flow control valves. The service life needs to be no less than 1 million times. Cannan received a hydraulic screw-in cartridge flow control valve recommended by their original supplier. It was a valve equivalent to HydraForce standard part and all parameters met his hydraulic unit operating conditions. Cannan greatly appreciated the recommendation of this hydraulic cartridge valve supplier, because this standard part can be used instead of customizing the hydraulic cartridge flow control valve specially. 

What Cannan didn't expect was that after the hydraulic unit had been running for about 6 months, they received customer complaints about several hydraulic cartridge flow control valves leaking. At the beginning, Cannan thought that it was just an isolated case.
