PILOT OPERATED CHECK VALVE
Overview
Symbol
Description
The PC10-34 is a screw-in, cartridge style, pilot operated, hydraulic
check valve
Operation
The cartridge valve allows free flow from ports 2 to 3, while normally
blocking flow from ports 3 to 2. Flow will be allowed from ports 3 to 2
when pressure is applied at port 1
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.
