PFR0.S08 VALVE SERIES
SAE Cartridge - 250 bar
Solenoid Valve
2 way proportional flow control
DESCRIPTION
The PFR0 is a proportional solenoid operated, twoway, 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.
