HydraForce PC08-30 Check Valve, Pilot-to-Open

HydraForce PC08-30 screw-in, cartridge-style, pilot-operated, hydraulic check valve for use in blocking or load-holding circuits.

The PC08-30 allows flow from 2 to 3, while normally blocking flow from 3 to 2. Flow will be allowed from 3 to 2 when sufficient pressure is applied at 1. The cartridge has a 3:1 pilot ratio, meaning that at least one-third 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.
