Rotatable Threaded Preloaded Electric Globe Valve

The rotatable threaded pre-tightening electric globe valve designed by Dazhong Valve Group, the valve is installed on the water and steam pipelines, and is used as an opening and closing device. The valve must be in a fully open or fully closed state, and cannot be used as a regulating valve. Driven by electric device. The sealing ring is made of formed flexible graphite ring, the valve seat is embedded in the valve body, and the plane is sealed.

• 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 opening and closing of the valve is driven by an electric device.

• Adopt pressure self-tightening sealing structure. The large nut can be rotated to pre-tighten the sealing ring. The sealing ring is made of a formed flexible graphite ring. The higher the medium pressure, the better the sealing performance.

• The valve seat is embedded in the valve body, with a flat seal. The valve seat and valve disc sealing surface are all made of drill-based cemented carbide plasma spray welding, which is wear-resistant and scratch-resistant. The surface of the valve stem is nitrided with corrosion resistance. deal with.

• The electric device is mainly composed of a special 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 flow of the medium flows from top to bottom
