DAPC10-32 Check, Pilot-to-Open

DESCRIPTION

A screw-in, cartridge-style, pilot-operated, hydraulic check valve for use in blocking or load-holding circuits.

OPERATION

The DAPC10-32 allows flow passage from 2 to 3，while normally blocking flow from 3 to 2 . Flow will be allowed from 3 to 2 when pressure is applied at 1.
The cartridge has a 4:1 pilot ratio, meaning that at least one-fourth of the load pressure held at 3 is required at 1 to open the valve. The check is spring-biased to assure holding in static or no-load conditions.A sealed pilot piston option is available.
Note: Special higher bias spring values available. Consult factory.

FEATURES

● Hardened seat for long life and low leakage.
● Optional sealed piston.
● Industry common cavity.
