A water solenoid is an electromagnetic device used to control the flow of water in hard-to-reach or remote locations. It consists of a poppet valve operated by a solenoid that opens the valve when activated by an electric current. The solenoid is commonly used in automated systems, such as fire and sprinkler systems.
A water solenoid is a remotely operated electromagnetic fluid control device used to shut off or allow the passage of water in a variety of applications. These solenoids typically consist of a standard poppet-type water valve operated by a solenoid mounted on top of the valve body. When the solenoid is activated, it pulls the valve poppet against the spring tension, opening the valve and letting water through. When power to the solenoid is cut off, the valve spring repositions the poppet closing the valve as it does so. The water solenoid is typically used where the valves are in hard to reach, dangerous or remote locations and where the operation of the valve is controlled by an automated system.
Solenoid valves are fluid control devices widely used in applications that require remote or automated activation of valves. A solenoid is a very simple actuator that relies on electromagnetic force to generate its working motion. The medium solenoid consists of a coil of wire wrapped around a hollow core. A movable ferrous metal plunger is placed near the core opening. When an electric current is passed through the coil, a powerful magnetic field is generated which attracts the plunger, intelligently pulling it into the core and producing the required output motion.
In the case of a water solenoid, the plunger is attached to the stem of a conventional poppet valve. When the solenoid is actuated, the movable plunger lifts the poppet off its seat against spring pressure, opening the flow path through the valve. If power to the coil is interrupted, the valve spring snaps the poppet into its seat, simultaneously closing the valve and resetting the solenoid. The water solenoid is typically a one-piece unit with the solenoid permanently mounted on top of the valve body. In some cases, the valve and solenoid are sealed in a common housing with only the water inlet and outlet fittings and solenoid coil wires visible.
The water solenoid is commonly found in applications where the valve location is in an inaccessible, remote, or dangerous location. In some cases, the valve can be manually activated by an operator from a centralized control station. It is also used extensively in automated applications such as fire and timed sprinkler systems. Magnetos are also useful in large, complex systems with a large number of valves and high operating cycles.
