PC10-34 Valve


SYMBOL:
PC10-34 Valve symbol
DESCRIPTION
A screw-in, cartridge-style, pilot-operated, hydraulic check valve for use in
blocking or load-holding circuits.

OPERATION
The PC10-34 allows free flow from 2 to 3, while normally blocking flow from 3 to 2.
Flow will be allowed from ports 3 to 2 when pressure is applied at 1.
The cartridge has a 7:1 pilot ratio.
The check is spring-biased to assure holding in static or no-load conditions. A sealed
pilot piston option is available.

FEATURES
• Higher pilot ratio reduces valve "chatter" in low flow applications.
• Choice of several bias spring values.
• Hardened seat for long life and low leakage.
• Optional sealed piston.
• Industry common cavity.
