Electric Actuated Butterfly Valve

Electric Actuated Butterfly Valve, also known as a proportional electric butterfly valve, operates such that the valve opening is proportional to the controlled fluid flow rate, or expressed as a percentage. It consists of an intelligent electric actuator and a butterfly valve body, controlled by a 4-20mA input/output signal. This valve is primarily used for regulating flow rate, pressure, temperature, and other parameters in various industrial automation piping systems.
