Valve Dimensions (See additional photos): L: 87mm, H: 114mm Max Power Consumption: 14w@12v/24v, 26w@110v/220v DFD Solenoid Valves are used to stop or open flow to a pipeline in one direction. They open/close with some pressure assistance needed from the working fluid. They do no stop flow in the backwards direction (against the arrow) and do not allow for full flow in the backward direction. A check valve should be utilized with this valve if backflow is cannot be permitted.
