Operation Symbol of ISV12-20 Poppet 2-Way N.C. Solenoid Valve

When de-energized, the ISV12-20 acts as a check valve, allowing flow from ① to ②, while blocking flow from ② to ①. When energized, the cartridge's poppet lifts to open the ② to ① flow path. In this mode, flow from ① to ② is severely restricted.


Operation of Manual Override Option


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