SYMBOL:
MP08-20 Valve symbol

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

OPERATION
The MP08-20 blocks flow from 2 to 1 flow path until an operator pulls the shaft outward.
Note: Pressure at port 1 will directly act on the spool and spring. Port 1 is intended to be
a tank port only.
The bias spring allows for up to 12.4 bar (180 psi) back-pressure at 1 before the valve will open.

FEATURES
• Hardened seat for long life and low leakage.
• Remains closed to 12.4 bar (180 psi) back-pressure.
• Compact, industry-common cavity.
