HYMP08-40 (Manual Cartridge Valve)

A cartridge-style manual 4-way, pull-to-shift, directional valve.


In its steady-state, spring-offset position, the valve directs flow from ③ to ②, and from ④ to ①. In the actuated (pulled) position, the cartridge directs flow from ③ to ④, and from ② to 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. Series operation is prohibited due to the tank port ① pressure rating.

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 ②, ③ and ④ (on ②, ③ and ④): 240 bar

Port ① max pressure (on ① max.): max. at 14 bar
