DACV16-20 Check Valve

DESCRIPTION

A screw-in, cartridge-style, hydraulic check valve for use as a blocking or load-holding device.

OPERATION

The DACV16-20 allows flow passage from 1 to 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 1 to open to 2 .

FEATURES

● Hardened seat for long life and low leakage.
● Optional bias springs for back-pressure application flexibility.
● Industry common cavity.
