Product Operation Symbol
When de-energized, the 22DH-C10 acts as a check valve, allowing flow from 1 to 2 but blocking passage from 2 to 1. When the cartridge is energized, the poppet rises to reveal the 2 to 1 flow channel. In this case, flow from one to two is likewise acceptable.
The Manual Override Option: How to Use It.
To override, insert button, turn it 180 degrees counterclockwise, and then let go. In this position, the valve will remain open. To return to normal operation, depress the button, turn it 180 degrees clockwise, and then depress it again. Override will be imprisoned as a result of this.
