DESCRIPTION

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

OPERATION

The DACV10-20 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.

● Fully guided check assembly.

●  Industry common cavity.
