The first thing you need to know about the electric ball valve is that it uses a solenoid to control the flow of fluid through a pipe, for example. This means that there are no moving parts in the valve itself. Instead, electricity passes through two coils of wire inside the solenoid which generate magnetic fields on either side of the coil's core--the interaction between these fields causes metal balls suspended by springs to move up or down with respect to one another, opening or closing off selected ports in order to regulate flow. The electric ball valve is a type of control valve that alters the flow of fluid in one direction. It also has two ports, an input port and an output port. This design enables it to be used as either a shutoff or regulating device. The ball valve is operated with the use of an actuator which can be electrically or pneumatically powered.
