DIRECTIONAL VALVES

MP08-20 Manual, Spring Return, Pull-to-Open

DESCRIPTION

A manual, 2-way, pull-to-open, screw-in hydraulic directional valve.

OPERATION

The MP08-20 blocks ﬂ ow from ➁ to ➀ until an operator pulls the shaft outward.

Note: Pressure at port

➀ will directly act on the spool and spring. Port ➀ is

intended to be a tank port only.

The bias spring allows for up to 12.4 bar (180 psi) back-pressure at

➀ before the valve

will open.

FEATURES

• Hardened seat for long life and low leakage.

• Remains closed to 12.4 bar (180 psi) back-pressure.

• Industry common cavity.
