HYMP08-30 (Manual Cartridge Valve)

A cartridge-style manual 3-way pull-to-shift directional valve.


In its steady-state, spring-offset position, the valve directs flow from ② to ①, while blocking at ③.

In the actuated (pulled) position, the cartridge directs flow from ③ to ②, blocking ①. The spring chamber is vented at ①.

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.



Operating pressure:

Port ③&②: 240 bar; port ① max: 14 bar
