Electric Wafer Type Butterfly Valve is a kind of electric butterfly valve, which is composed of electric device and Wafer Type Butterfly Valve, and can achieve automatic control. Electric Wafer Type Butterfly Valve has short structure length, small volume and light weight. Electric butterfly valve is able to switch butterfly valve remotely in the control room, without the need for people to go to the scene to close the valve, saving time and effort, installed in dangerous occasions, but also to achieve safe production.
Electric Wafer Type Butterfly Valve has two kinds of hard seal butterfly valve and soft seal butterfly valve, hard seal electric butterfly valve seat sealing surfacing temperature and corrosion resistant alloy materials, with high pressure resistance, high temperature resistance and other characteristics. Soft seal electric butterfly valve seal is rubber or PTFE material, used in low pressure pipeline, less than PN1.6, for oil, water, powder and other media.
