Collection: Main & Relief Valves

Main & Relief Valves are listed here for applications including excavators, loaders and vehicles. They control direction, pressure, flow or actuator movement in hydraulic, pneumatic, fuel and air systems. Because manufacturers can revise function, pressure range, port pattern, thread, pilot ratio, actuation method and default state, confirm the exact equipment configuration before planning a repair.

Product records place these items beside engine, fuel-system and hydraulic systems; record the fitted configuration before comparing alternatives. Photograph connectors and mounting points before removal.

• Start with the listed part number, machine model and installation position.
• Compare valve function and default state, port pattern and thread and pressure or flow range.
• Confirm actuation method, body dimensions and the supplied pieces.

For Main & Relief Valves, check supplied components and stated applications. Follow the manufacturer's inspection, installation and testing procedure.

Fitment FAQ: Should the old component be measured? Yes, when the reference is uncertain; include port pattern and thread and pressure or flow range in the comparison.

Resolve uncertain references before ordering. Eligible returns follow the published 90-day return policy.
