Electric Stop Valve For Power Station

The electric globe valve specially designed by Dazhong Valve Group is installed on the water and steam pipelines 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. The sealing ring adopts a formed flexible graphite ring. The valve seat is embedded in the valve body, and the flat seal is used. The valve seat and the valve disc sealing surface are all made of drill-based cemented carbide plasma spray welding, and the surface of the valve stem is treated with anti-corrosion nitriding.

• The valve is installed on the water and steam pipeline 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. It adopts a pressure self-tightening sealing mechanism, and the sealing ring is formed of 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. Both the valve seat and the valve disc sealing surface are made of drill-based cemented carbide plasma spray welding, which is wear-resistant and has good scratch resistance. The surface of the valve stem is resistant to corrosion. Nitriding.

• The flow of the medium is from up and down (reverse flow).

• The opening and closing of the valve disc is controlled by an electric device mounted on the valve cover. The electric device is equipped with a valve motor, a reduction box, and a torque control mechanism to control the opening position of the valve. Flashing indicator, the operator can know the valve opening and closing status at any time.

• When the valve is closed, use the torque limiting mechanism to adjust the closing position of the valve, and adjust the stroke control mechanism as protection. When the valve is opened, use the stroke control mechanism to control the opening position of the valve, and adjust the torque limiting mechanism for protection.

• The valve can be switched between hand, electric and manual. Turn the handwheel clockwise to close the valve. If there is a flashing indicator on the console, the operator can know the opening and closing of the valve at any time
