Water solenoid valves control the flow of water through a piping system using a piston or tappet valve and a solenoid coil. When the solenoid is activated, the valve opens, allowing water to flow through. They are used in smaller water supply systems and can be made of various materials. Solenoids are typically mounted on top of the valve body and generate low power outputs, making them suitable for light applications.
A water solenoid valve is a fluid flow control device used to allow or restrict the flow of water through a piping system. They are usually one-piece units consisting of a piston or tappet valve and a solenoid coil. The valve stem is attached to the solenoid plunger so that when the solenoid is actuated, the valve mechanism opens allowing water to flow through it. When power to the solenoid is cut off, a valve return spring returns the piston to its seat, cutting off the flow of water and resetting the solenoid. Solenoid valves are typically used on smaller water supply systems such as those found in washing machines, home and agricultural irrigation and light industrial systems.
Solenoid valves operate much like conventional valves, the only real difference being that a solenoid actuates the valve mechanism and not operator input. Due to the linear actuating motion output of the solenoids, the valves themselves are typically of the vertical lift piston or poppet type. Depending on the intended operating specifications of the water solenoid valve, it may be constructed of corrosion resistant metals such as brass or stainless steel or be made of various grades of plastic. Solenoids can be equipped with coils rated for mains voltage alternating current (AC) supplies or low voltage direct current (DC) supplies.
Most examples of water solenoid valves are packaged units with the solenoid mounted on top of the valve body. The solenoid plunger is connected to the valve stem or both can form one integral unit. When the solenoid is activated, the plunger is pulled very rapidly up into the coil core. As it moves, it lifts the stem and piston away from the valve seat allowing water to pass through. The valve stem is spring loaded and is lifted against spring tension during actuation.
When power is removed from the water solenoid valve coil and the plunger is released, the tension built up in the spring intelligently pushes the valve plunger back into its seat, shutting off the water flow and resetting the solenoid in preparation for cycling following. Solenoids usually generate relatively low power outputs compared to other types of actuators. For this reason the water solenoid valve is generally used in fairly light applications. These include valves for household appliances in washing machines and dishwashers, small sprinkler systems and light engineering or industrial systems. Applications with more powerful valves typically use higher output actuators, such as electric gear motors and rotary hydraulic types.
