A manual, 2-way, pull-to-open, screw-in hydraulic directional valve.
The MP08-20 blocks flow 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.
• Hardened seat for long life and low leakage.
• Remains closed to 12.4 bar (180 psi) back-pressure.
• Industry common cavity.
