DIRECTIONAL VALVES
MP10-43 Manual, Spring Return, Pull-to-Shift
DESCRIPTION
A 4-way, manual, pull-to-shift, spring-return, screw-in, directional hydraulic cartridge
valve.
Series operation is prohibited due to the tank port (
➀) pressure rating.
OPERATION
In its steady-state spring-offset position, the MP10-43 blocks fl ow at ➂ and at ➁,
while
➃ is open to ➀. In the actuated (pulled) position, the cartridge directs fl ow from
➂ to ➃ and from ➁ to ➀. Note that all ports are restricted/open in transition.
Note: Pressure at port
➀ will directly act on the spool and spring. Port ➀ is
intended to be a tank port only.
A unique pull-and-rotate feature for a positive actuated position hold 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 90° turn from the locked actuated position.
FEATURES
• Hardened spool and cage for long life.
• Remains closed to 10.3 bar (150 psi) back-pressure.
• Optional rotational lock position.
• Industry common cavity.
