PFR0.S08
SAE Cartridge - 250 bar
Proportional Solenoid Valve
Description
The PFR0 is a proportional solenoid operated, two way, poppet type, normally closed, screw-in hydraulic cartridge valve for low leakage blocking and load-holding applications. When de-energized, the valve operates as a check valve and allows flow from 1 to 2, while blocking flow from 2 to 1. When energized, the valve opens 2 to 1 flow path: flow is proportional to the current applied to the coil.
