A solenoid is an electromechanical valve for use with a liquid or gas. The valve is controlled by an electric current through a solenoid valve in case of a two-port throughput is on or off, in the case of a three-way valve is leaking switch between the two output ports. Multiple valves can be placed together on a manifold.
The valves are control elements most commonly used in fluids. Their task is to turn off, release, dose, distribute or mix fluids. They come in many applications. Solenoids offer fast and safe switching, high reliability, long life, good compatibility with materials used, the power to control low and compact.
In addition to the actuator piston type which is used most is pivoted armature actuators and rocker actuators also used.
The solenoid has two main parts: the solenoid and the valve. A solenoid converts electrical energy into mechanical energy, which in turn opens or closes the valve mechanically. Direct Acting Valve is only a small flow circuit, as shown in Section E of this diagram (this section is described below, the control valve). This film tells the valve is piloted in a small stream using the flow through a hole much bigger.
Solenoid valves may use the seal or rubber seals, and may also have electronic interfaces for easy control. In the spring of the valve can be opened or closed when the valve is not activated.
Solenoid valves used in hydraulic and pneumatic systems, hydraulic actuators, hydraulic motors or more industrial valves. Automatic sprinkler systems also use irrigation valves with automatic regulator. Washing machines and dishwashers household use solenoid valves to control water entering the machine. In the paintball industry, the solenoid valves are normally referred to simply as "Atmospheres." They are commonly used to control a large valve used to control fuel (usually compressed air or CO2). The solenoid valves are used in the dental chair to control air. In industry [State], the "magnet" also refer to an electromechanical solenoid commonly used to turn an etching
