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 MP10-43 blocks flow at ports 3 and 2 while 4 is open to 1.
In the actuated (pulled) position, the cartridge directs flow from 3 to 4 and from 2 to 1.
Note that all ports are restricted but open in transition.
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.
• Remains closed to 10.3 bar (150 psi) back presssure.
• Optional rotational lock position.
• Industry-common cavity.
