HYSV12-28 (2/2 Solenoid Valve, Non-Return Type)

A solenoid operated, 2-way, 2-position, normally closed, poppet-type bi-directional cartridge valve.


When de-energized, the valve blocks flow in both directions. When energized, the cartridge’s spool shifts to allow flow in both directions.

To override, push button in, twist counterclockwise 180° and release. In this position, the valve will remain open in a detented condition. To return to normal operation, push button in, twist clockwise 180° and release. Override will be detented in this position.



Max. operating pressure:

240 bar
