CV12-21 Check Valve (CV12-21)

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

Product Operation

The CV12-21 allows flow passage from ➁ to ➀, while blocking flow from ➀ to ➁The cartridge has a fully guided check which is spring-biased closed until suffi cient
pressure is applied at ➁ to open to ➀

Product Features

• Low check mass for anti-cavitation applications.
 Hardened seat for long life and low leakage.
 Optional bias springs for back-pressure application flexibility.
 Cost-effective cavity.
