AAK Hydraulic Cartridge Relief Valve has no worries in 18 months, while the competitor PK with AAK c

Devante is from a hydraulic equipment company in Spain. In June last year, a batch of hydraulic cylinders of their company were complained of telescoping jitter. During after- sales service, it was judged that the hydraulic cartridge relief valve of the hydraulic system was abnormal. After disassembly, it was found that the spring elasticity in the valve body was out of function. The manufacturer of the hydraulic cartridge relief valve thought that the high working frequency of oil cylinder caused spring failure.

At the beginning of last year, their engineer required the manufacturing quality of the hydraulic cartridge relief valve for the hydraulic cylinder they developed, to benchmark HydraForce. Devante believed that the function of this hydraulic cartridge relief valve is relatively conventional, so he chose a hydraulic cartridge relief valve manufacturer with competitive price.
