Releasable (Piloted) Check Valves

Releasable check valves are used in hydraulic circuits to provide a positive lock with directional spool valves, as a hydraulically actuated drain, or idle circulation valves. CRH and RHC valves are screw in valve cartridges. The RHC version is available with or without pre-release for high pressure and high-actuator flows. RH valves are used for blocking one or two actuator lines.

Pre-fill Valves

Check and pre-fill valve type F enables free flow in one direction and blocks the flow in the opposite direction. This valve is used as a high-flow valve in top ram presses for quickly draining and replenishing press cylinders during opening and closing in rapid traverse mode. The smaller sizes may be optionally equipped with a pre-relief device to prevent pressure surges during decompression.
