Proportional Solenoid Valves - Cartridge Style
PFR0.S08
SAE Cartridge - 250 bar
Proportional Solenoid Valve
2 way proportional flow control
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.
Technical Features
All External surfaces are zinc plated and corrosion proof. All valve parts are made of high strength steel. Poppet and seat are hardened and micron finished to guarantee minimal wear and to extend service life. Efficient wet armature design. Industry SAE common cavity.
