DIRECTIONAL VALVES
MP58-30 Manual, Spring Return, Pull-to-Shift
DESCRIPTION
A 3-way, manual, pull-to-shift, spring-return, 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 MP58-30 directs fl ow from ➁ to ➀, while
blocking at
➂.
In the actuated (pulled) position, the cartridge directs fl ow from
➂ to ➁, blocking ➀.
The spring chamber is vented at
➀.
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 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
➀.
• Optional rotational lock position.
• Compact size.
