MP08-34 Valve

MP08-34 Valve symbol

A manual, 3-way, pull-to-shift, spring-return, screw-in hydraulic directional valve.

In its steady-state, spring-offset position, the MP08-34 blocks flow from 2 to 3.
In the actuated (pulled) position, the cartridge directs flow from 3 to 2.
The spring chamber is vented at 1. When released, the valve returns to its steady state.
Note: Pressure at port 1 will directly act on the spool and spring.
   Port 1 is intended to be a tank port only.

• Hardened spool and cage for long life.
• Pressure to 14 bar (200 psi) on port 1.
• Optional rotational lock position.
• Compact, industry-common cavity.
