DIRECTIONAL VALVES
PC10-32 Check, Pilot-to-Open, 2:1 Pilot Ratio
DESCRIPTION
A screw-in, cartridge-style, pilot-operated, hydraulic check valve for use in blocking
or load-holding circuits.
OPERATION
The PC10-32 allows fl ow passage from ➁ to ➂, while normally blocking fl ow from
➂ to ➁. Flow will be allowed from ➂ to ➁ when pressure is applied at ➀.
The cartridge has a 2:1 pilot ratio, meaning that at least one-half of the load pressure
held at
➂ is required at ➀ 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.
