DESCRIPTION
A screw-in, cartridge-style, pilot-operated, hydraulic check valve for use in blocking or load-holding circuits.
OPERATION
The PC10-32 allows flow 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 2:1 pilot ratio, meaning that at least one-half 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.
FEATURES
• Hardened seat for long life and low leakage.
• Optional sealed piston.
• Industry common cavity.
