Check Valves (Pilot-Operated)
Pilot-operated check valves provide reliable hydraulic flow control by using an external pilot signal to open the valve and allow flow. Once pilot pressure is removed, the valve reseals to prevent reverse flow. These valves are ideal for applications requiring load holding, counterbalance, and overrun protection. Hydraulic Supply offers a wide range of pilot-operated options in both cartridge and inline formats, with flow ratings up to 24 GPM and pressure ratings up to 6000 PSI.

Common Uses for Pilot-Operated Check Valves
These valves are critical for equipment that demands precise control over flow direction and pressure stability. Key use cases include:
-
Mobile Machinery & Equipment – to maintain load position in lifting or articulating components
-
Construction – for preventing unintended movement in hydraulic cylinders
-
Oil & Gas – to manage pressure differentials in downhole and surface applications

Pilot-Operated Check Valve FAQs
What Is a Pilot-Operated Check Valve?
A pilot-operated check valve stays closed until pilot pressure is applied, allowing flow in one direction and preventing reverse flow.
How Does a Pilot-Operated Check Valve Work?
A pilot-operated check valve opens when pilot pressure is applied, allowing flow in one direction. When the pressure is removed, a spring closes the valve to prevent reverse flow and maintain system stability.
When Should You Use a Pilot-Operated Check Valve?
Use these valves in load-holding systems, counterbalance circuits, and any application where controlled directional flow is required.
What Flow and Pressure Ranges Are Available?
Hydraulic Supply offers models up to 6000 PSI and 24 GPM, in both cartridge and inline configurations.
