CHECK VALVE

Overview

Description

The CV10-20X is a screw-in, cartridge style, hydraulic check valve for use as a blocking or load-holding device

Operation

The CV10-20X allows flow passage from port 1 to port 2, while normally blocking oil flow in the opposite direction. The cartridge has a fully guided check which is spring-biased closed until sufficient pressure is applied at port 1 to open to port 2

Features

  • Hardened seat for long life and low leakage.
  • Optional bias springs for back-pressure application flexibility.
  • 300 psi bias spring option with tall cap available.
  • Fully guided check assembly.
  • Industry-common cavity.
