MP08-30 Manual, Spring Return, Pull-to-Shift (MP08-30)
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.
Product Operation
In its steady-state, spring-offset position, the MP08-30 directs flow from ➁ to ➀, while blocking at ➂In the actuated (pulled) position, the cartridge directs flow from ➂ to ➁, blocking ➀. The spring chamber is vented at ➀Note: 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.
Product Features
• Hardened spool and cage for long life.
• Pressure to 14 bar (200 psi) on ➀
• Optional rotational lock position.• Compact size.
