PILOT OPERATED CHECK VALVE WITH OPTIONAL THERMAL RELIEF

Overview

Description

The PCV10 is a pilot operated, hydraulic check valve for use in blocking or load holding circuits

Operation

The valve allows flow from port "b" to "a" ports, while normally blocking flow in the opposite direction. Flow will be allowed from "a" to "b" when pressure is applied at port "x". The valve has 4:1 pilot ratio, so at least 25% of the load pressure held at port "a" is required at port "x" to open the flow valve. Optional thermal relief valve is available

Features

  • Hardened seat for long life and low leakage.
  • Optional sealed pilot piston.
  • Optional spring ranges.
  • Check section is serviceable as a cartridge.
