Description
The MP08-20X is a 2-way, manual pull to shift, spring return, screw-in, cartridge style directional
hydraulic valve
Operation
In the neutral position the MP08-20X valve blocks flow from port 2 to 1 until it is manually actuated
(pulled). When released the valve returns to its neutral position. The bias spring allows up to 180 psi
[12,4 bar] back pressure at port 1 before the valve will open
note: pressure at port 1 will directly act on the spring. Port 1 is intended to be a tank port only
Features
Hardened seat for long life and low leakage.
Remains closed to 12.4 bar (180 psi) back-pressure.
Compact, industry-common cavity.
