Pilot Operated Check Valve Cartridge series REPY

The pilot-operated check valves, series REPY…, are size 10, two stage, screw-in valves with an M32×1,5 mounting thread. The poppet seat design ensures that the valves are leak-tight from A1 to A. The check function can be overridden by applying a suitable pilot pressure at port X. In the flow direction A to A1, flow can pass freely through the screw-in valve (opening pressure >2 bar). The leakage-oil from the pilot piston is drained via port Y. This type series is used where the pressure in the A line can be more than 20 % of the pressure in X while the valve is piloted open (oil flow A1 to A). If this situation will not arise, series REP… cartridge check valves with internal leakage-oil drain can be used. All external parts of the screw-in valve are zinc-nickel plated, and are thus suitable for use in the harshest operating environments. These valves are mainly used in mobile and industrial applications as pilot valves for controlling the travel direction of actuators such as hydraulic motors and cylinders.
