Overview

Description

The PC08-30 is a screw-in, cartridge style, pilot operated, hydraulic check valve used for blocking or load holding circuits.

Operation

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

Features

  • Hardened seat for long life and low leakage.
  • Optional sealed piston.
  • Optional spring ranges.
  • Compact size.
