CHECK VALVE

Overview

Description

The CV04-20 is a screw-in, cartridge style, hydraulic check valve for use as a blocking or load-holding device

Operation

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