DGMPC-H8 Pilot Operated Check Valves

The DGMPC hydraulic operated check valve is of a sandwich plate design. They are used for leak-free closure of one or both service ports, even for long periods of time. Free flow occurs from A1 to A2 or B1 to B2. Flow in the opposite direction is blocked. The fluid flows from A1 to A2, the piston (1) is pressurized and is pushed to the right, thereby opening the ball poppet (2) which then opens the main poppet (3). In order to ensure correct closing of the valve, the service ports of the directional valve must be connected to tank in the neutral position (see typical circuit).

Features:

• Industry Standard Mounting, ISO 4001-8, NFPA T 3.51 M R1 and ANSI B 93.7 D08
• For use in vertical stacking assemblies
• For the leak free closure of one or both service ports
