These modular valves are available with the pilot operated check valve facility on either A or B or both A and B ports. The hydraulic opening operation for free flow in reverse direction is achieved by means of internal pilot pressure available from the other working port.
To ensure proper closure of both valve poppets, both user connections should be unloaded when the control valve is in the neutral position by connecting with the return line.
Seat type valves with free flow from port A to port B.They give leak free closure in opposite direction.
Opening of the flow direction B to A is effected by pressurisation of pilot piston at port X.
Three sizes in both Threaded & Subplate mounting.
Subplate mounting interface conforms to ISO 5781.
