Product Operation Symbol
When the 22DH-A10 valve is not energized, it acts as a check valve, allowing flow from position ① to position ② while blocking flow from position ② to position ①. However, when the valve is energized, the poppet within the valve core rises, opening the flow path from position ② to position ①. In this mode, flow from position ① to position ② is also allowed. The valve has a manual override feature for operational control. To activate override, press the button and turn it 180° counterclockwise, then release. In this position, the valve will remain open regardless of power status. To return to normal operation, press the button, turn it 180° clockwise, and release it. In this state, the override will be securely positioned and the valve will resume its normal operation.
