Description<br />
A screw-in cartridge, pressure sensing valve with multifunction potential when<br />
used with flow, pressure and directional control devices. It can be used as<br />
high flow switching or metering element, main stage for pilot operated relief or<br />
sequence valve.<br />

Operation<br />
Pilot flow through the spool orifice, from port 1 to port 3 creates a pressure drop<br />
and allows flow from port 1 to port 2 when the pressure drop exceeds the spring<br />
bias pressure. The valve can be remotely controlled at port 3 such as relief or<br />
solenoid valve.<br />
Features<br />
• Operating pressure up to 5000 psi (350 bar)<br />
• Various bias spring settings up to 300 psi (20.7 bar)<br />
• Quiet, modulated response<br />
• All external surfaces zinc-plated<br />
• Hardened spool and sleeve to ensure minimal wear and extend service life<br />
• Industry common cavity<br />
