Electric Gate Valve With Middle Flange

The electric gate valve with middle flange designed by Dazhong Valve Group has double gate plates and the branch pipes at both ends are welded. The closing mechanism is mainly composed of wedge-type double gates that can be adjusted, universal top, clamping ring, etc. The valve seat and valve disc sealing surface are made of drill-based cemented carbide plasma spray welding, and the surface of the valve stem is treated with anti-corrosion nitrogen. The opening and closing of the door is controlled by an electric device mounted on the valve cover. The electric device is equipped with a special motor for the valve, a reducer, a torque control mechanism, a field operation mechanism, a stroke control mechanism, and an electric switching mechanism.

• Installed on water and steam pipelines, used as an opening and closing device. It adopts a pressure self-tightening sealing structure, and the double gates and the branch pipes at both ends are welded.

• The closing mechanism is mainly composed of self-aligning wedge-type double gates, universal tops, clamping rings, etc., which are guided by the guide ribs in the valve body to move up and down.

• The valve seat and valve disc sealing surface are made of drill-base cemented carbide by plasma spray welding, with good wear resistance and friction resistance.

• The surface of the valve stem is treated with anti-corrosion nitriding, which has good corrosion resistance and scratch resistance.

• The opening and closing of the valve is controlled by an electric device mounted on the valve cover. The electric device is equipped with a special motor for the valve, a reducer, a torque control mechanism, a field operation mechanism, a stroke control mechanism, and an electric switch. In addition to local operation, remote operation can also be carried out.
