HYSV12-21 (2/2 Solenoid Valve, Normally Open)

Description:
A solenoid operated, 2-way, 2-position, normally open, poppet-type cartridge valve.

Operation:

When de-energized, the valve allows a flow from ② to ①, flow from ① to ② is severely restricted in this mode.

When energized, the valve’s poppet closed on its seat, blocking flow from ② to ①. The cartridge will allow ① to ② flow after overcoming the solenoid force.

 

Operation of manual override option:

To override, push button in to activate. To return to normal valve function, release button.
