Pilot operated check valve NG6 AM3.UP1.A.5 - Aron-Dana

A pilot operated check valve can be used to allow free flow in one direction by raising a conical seated poppet valve, while in the opposite direction the fluid can return by means of a small piston piloted by the other line pressure (piloted side). These valves prevent that a cilinder is moving as result from external forces, also they can act like a brake function. Pilot operated check valves are available in single and double lines.
