PC10-34

PILOT OPERATED CHECK VALVE

Overview

Description

The PC10-34 is a screw-in, cartridge style, pilot operated, hydraulic check valve

Operation

The cartridge valve allows free flow from ports 2 to 3, while normally blocking flow from ports 3 to 2. Flow will be allowed from ports 3 to 2 when pressure is applied at port 1

Features

  • Higher pilot ratio reduces valve "chatter" in low flow applications.
  • Choice of several bias spring values.
  • Hardened seat for long life and low leakage.
  • Optional sealed piston.
  • Industry common cavity.
