For PILOT OPERATED RELIEF VALVE equivalent to HydraForce RV12-26, a Russian customer placed the re-orders with AAK 3 times in half a year

China [CN]

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:

l Adjustments cannot be backed out of the valve.

l Adjustments prohibit springs from going solid.

l Hardened spool and cage for long life.

l Optional spring ranges to 240 bar (3500 psi).

l Rapid, smooth response to pressure surges.

l 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 Valve:

Max. Operating Pressure: 241 bar (3500 psi)

Flow: See PRESSURE DROP VS. FLOW graph

Internal Leakage: 115 ml/min max. at to 85% of nominal setting

Operating Fluid Temperature: - 40 °C to 120 °C (with Standard Buna N seals)

Cavity: 12-2 

The newly launched AAK E-RV12-26 hydraulic pilot operated cartridge relief valve, benchmarking HydraForce RV12-26, has been approved by customer in Russia after 1 year of testing. You are welcome to try it out.
