Electric centerline butterfly valves
Summary
Electric center line butterfly valve is made up of butterfly valve and electric actuator, input control signal (4~20mA or 1~5V DC) and single~phase power to control the operation. It is strong function, small, light, reliable performance, simple matching, big flow capacity. It’s especially suitable for the viscous medium which contains particles, fibrous nature of the occasion. It widely applies to industrial automatic control system such as food, pro~environment, light industry, petroleum, paper making, chemical industry and electricity.
