AAK Hydraulic Relief Valve Benchmarking HydraForce RV12-26

This Monday, we launched a hydraulic cartridge pilot operated relief valve
equivalent to HydraForce standard part RV12-26.

It is a screw in, cartridge style, pilot operated (two stage), spool type
relief valve, intended for use as a pressure limiting device in demanding
hydraulic circuits which require fast response and low hysteresis.

The features of this hydraulic cartridge pilot operated relief valve:
Adjustments cannot be backed out of the valve.
Adjustments prohibit springs from going solid.
Hardened spool and cage for long life.
Optional spring ranges to 240 bar (3500 psi).
Rapid, smooth response to pressure surges.
Cost-effective cavity.

A hydraulic cartridge valve customer in Russia placed a test order for 10 pcs
last January in 2022. After 1 year of testing, it proves that the function and
performance of AAK hydraulic pilot operated cartridge relief valve benchmarked
the quality of HydraForce RV12-26. Till now, we have received their re-orders 3
times since 2023.

AAK hydraulic pilot operated cartridge relief valve 2 advantages:
1. Internal leakage: 115ml/min, benchmarking against HydraForce
2. Its service life is 2 times that of its peers

Technical parameters of AAK E-RV12-26 Hydraulic Pilot Operated Cartridge Relief
