MP10-22 Manual, Spring Return, Pull-to-Open (MP10-22)
A manual, 2-way, normally closed, pull-to-open, spring-return, screw-in, hydraulic cartridge, system unloading valve for higher tank pressure applications.
Product Operation
The MP10-22 blocks flow from ➁ to ➀ until an operator pulls the shaft outward.The bias spring allows for up to 27.6 bar (400 psi) back-pressure at ➀ before the valve will open.
When passing high flow rates, a combination of the differential pressure across the
valve (flowing ➁ to ➀) and ➁ downstream back-pressure may require the operator to push the shaft to close.
Note: Pressure at port ➀ will directly act on the spool and spring. Port ➀ is intended to be a tank port only.
A unique 90° rotational lock is optional for positive “open” position holding. The valve
resets to spring return-to-close with a 90° turn from the locked-open position.
Product Features
• Hardened seat for long life and low leakage.
• Remains closed to 27.6 bar (400 psi) back-pressure.
• Optional rotational lock position.
• Industry common cavity.
