High Performance Electric Butterfly Valve For Flow Control Wafer Type On Off
OVERVIEW
A butterfly valve is a valve used for flow regulation in large pipe diameters in which the disc takes the form of disk. Operation is similar to that of a ball valve. A plate or disc is positioned in the center of the pipe. The disc has a rod passing through it that is connected to an actuator on the outside of the valve. Rotating the actuator turns the disc either parallel or perpendicular to the flow. Unlike a ball valve, the disc is always present within the flow, therefore a pressure drop is always induced in the flow, regardless of valve position.
Electric center line butterfly valve is made up of butterfly valve and electric actuator . 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.
