Direct Acting, Double Check Valve - RPDR 06/08/10


The pilot-to-open double check valve RPDR is inline mounted with two opposing, direct-acting, spring-loaded poppet valves.

In the normal position, pressure on the closing element onto the valve seat happens. It is due to the spring and pressure at port C or D, and blocks flow from C to A or from D to B leak free. If there is a sufficient introduction of high control pressure at port A or B, the control piston moves. Then, it will lift the closing element off the valve seat. The valve opens and oil flows from D to B or from C to A.

  • The main applications are:

    • To prevent uncontrolled movement or creeping of loaded cylinders,

    • To isolate sections of the system

    • And to control double-acting cylinders

  • External surfaces zinc-plated and corrosion-proof
  • Hardened and ground internal valve components to ensure minimal wear and extended service life
  • Consumer holds in position with minimum leakage (A and B must vent to T)
