MP08-41 Valve

SYMBOL:

DESCRIPTION
A manual, 4-way, pull-to-shift, spring-return, screw-in hydraulic directional valve.
Series operation is prohibited due to the tank port (1) pressure rating.

OPERATION
In its steady-state, spring-offset position, the MP08-41 blocks flow in all directions.
In the actuated (pulled) position, the cartridge directs flow from 3 to 4, and from 2 to 1.
The spring chamber is vented at 1.
Note: Pressure at port 1 will directly act on the spool and spring.
   Port 1 is intended to be a tank port only.

A unique pull-and-rotate feature for holding the positive actuated position is optional.
A 90° rotation is required to position at the hold slot. The valve resets to spring-return
de-actuated with a slight pull and a 90° turn from the locked actuated position.

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