High Pressure Internal Thread Keyed Electric Globe Valve

The high-pressure internal thread keyed electric globe valve designed by Dazhong Valve Group, the valve is installed on the water and steam pipelines. It is used as an opening and closing device. The valve must be in a fully open or fully closed state. It cannot be used as a regulating valve. Driven by electric device. The valve body and bonnet are connected by internal thread and key. The valve seat adopts the inlaid structure, the valve seat and the valve disc sealing surface are all made of drill-based cemented carbide plasma, and the valve stem surface is treated with anti-corrosion nitriding.

• The valve is installed on the water and steam pipelines. It is used as an opening and closing device. The valve must be in a fully open or fully closed state. It cannot be used as a regulating valve. The valve is opened and closed by an electric device. Drive. , valve body, valve The cover is internally threaded and keyed.

• The valve seat adopts a mosaic structure, and the valve seat and valve disc sealing surface are all made of drill-based cemented carbide plasma spray welding, which has good wear resistance and scratch resistance.

• The surface of the valve stem is treated with anti-corrosion nitriding, which has strong corrosion resistance. It adopts a pressure self-tightening sealing mechanism. The higher the pressure, the better the sealing performance.

• The electric device is mainly composed of a special electric motor, a reduction box, a torque control mechanism, a stroke control mechanism, a field operation mechanism, a manual electric switching mechanism, etc. The closing position of the valve is controlled by a torque limiting mechanism, and the stroke control mechanism is used for protection; the valve The opening position is controlled by the stroke control mechanism and protected by the torque limit mechanism. In addition to the local operation, the valve can also be operated remotely.

• The valve can be installed anywhere on the pipeline, and the flow of the medium flows back from top to bottom
