MD10-40 Manual, Spring Return, Push-to-Shift (MD10-40)
A 4-way, manual, push-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 MD10-40 directs flow from ➃ to ➂, and from ➁ to ➀ (tank).In the actuated (pushed) position, the cartridge directs flow from ➁ to ➂, and from ➃ to ➀. Note that all ports are 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.
When the valve is actuated (pushed in) it can be detented by holding in and turning
the knob clockwise 90°. When released, the valve will remain in the actuated position.
To return the valve to its steady state, push in the knob and turn the handle
counterclockwise.
Product Features
• Hardened spool and cage for long life.
• Optional detent position.
• Industry common cavity.
