2-way valves (also known as 2-port valves) are on/off gates for fluid control. They automatically allow or block the flow of a single fluid line and are engineered to handle water, oil, heated water, steam, vacuum, and NSF61-certified drinking water. They offer high flow capacity in a light, compact body and have specialized power-saving coils that consume much less electrical power than older, traditional solenoid designs. They can be configured by port size, seal material, and pressure rating and are available in a variety of body materials such as brass, stainless steel, aluminum, and resin.
