Forklift Pressure Relief Valve MV-01 MV-02 MV-03

Forklift Pressure Relief Valve MV-01 MV-02 MV-03: Hydraulic System Overpressure Protection

The MV-series pressure relief valves are hydraulic safety components that protect forklift hydraulic circuits from overpressure damage. When system pressure exceeds the valve set point, the spring-loaded poppet opens and diverts excess hydraulic oil back to the tank, preventing burst hoses, damaged seals, and pump failure. Models MV-01, MV-02, and MV-03 cover different flow rate and port threading configurations for stackers, pallet trucks, and counterbalance forklifts. At just 0.3 kg and 10x5x2 cm package size, these compact inline valves install directly into the hydraulic manifold or port block without additional bracketry.

Each valve is a one-way, thread-insert type with standard port connections rated for 5 gpm flow range. Operating temperature range spans -20 to +80°C, suitable for cold storage and high-temperature engine bay environments. The simple spring-and-poppet design has no electronic components, making these valves reliable in dusty, high-vibration forklift applications. Common failure modes include spring fatigue causing premature relief opening (system cannot reach working pressure), stuck-closed poppet from debris (zero overpressure protection), and external leakage from the thread seal. Backed by a 1-year warranty.
