The Electric Welding Gate Valve is composed of welded gate valve equipped with electric actuator. Both ends of the branch pipe are welded structure. The middle part adopts the pressure self tightening type without valve cover, which is driven by the power supply of the electric device to make the valve stem move up and down, so as to control the opening and closing of the valve. The Electric Welding Gate Valve is mainly used in high-temperature and high-pressure occasions such as water, steam, oil products and superheated steam pipelines. The pressure is generally within pn25,0mpa, It has the advantages of high temperature resistance and corrosion resistance. Electric Welding Gate Valve can be operated directly or controlled remotely,
