DIRECTIONAL VALVES
MP10-20 Manual, Spring Return, Pull-to-Open
DESCRIPTION
A manual, 2-way, pull-to-open, screw-in hydraulic directional valve.
OPERATION
The MP10-20 blocks fl ow from ➁ to ➀ until an operator pulls the shaft outward.
The bias spring allows for up to 12.4 bar (180 psi) back-pressure at
➀ before the
valve will open.
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.
FEATURES
• Hardened seat for long life and low leakage.
• Remains closed to 12.4 bar (180 psi) back-pressure.
• Optional rotational lock position.
• Industry common cavity.
