Product Operation Symbol
When de-energized, the 22DH-A12 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 is also allowed from ① to ②.
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.
