Solenoid valves are used to convert electrical energy into mechanical energy.
Solenoid valves have quite a distinctive look about them. Once the valve is installed, the top part is the solenoid, and the bottom part is the valve, therefore making a solenoid valve.
The solenoid coil on the top is used to operate the valve, by passing an electrical current through it to create an electromagnetic field and operate the valve.
This means if it is connected to a controller, it can be operated autonomously and remotely by a computer without the need for engineers to physically run around opening and closing the valves. This allows systems to run much more efficiently and safety.
