Pilot Operated Check Valve

Pilot Operated Check Valve

Hydraulic valves designed to allow free flow in one direction while blocking the reverse flow of fluid until pilot pressure is applied

The pilot operated check valve is designed to allow free hydraulic fluid flow in one direction while blocking reverse flow to securely hold or lock the actuator’s position. When the pilot pressure is applied, the valve opens to permit reverse fluid flow, enabling controlled actuator movement. This design ensures reliable load holding and precise control in various hydraulic systems, improving operational safety and efficiency in mobile and industrial machinery applications.

Features
  • Modular, compact design engineered for safe and reliable load holding in hydraulic systems
  • Available in multiple flow capacity options, suitable for diverse installation requirements across various machinery applications
