Product features

The electric flange stop valve (J941H) has good strength, rigidity and flow capacity. It is composed of an electric actuator and a flange stop valve. It receives the AC380V power supply pressure or voltage signal to complete the rising or falling opening and closing action. The electric flange stop valve has good strength, rigidity and flow capacity. It can be used in various pressure, temperature and medium working conditions. It is widely used in environmental protection, petroleum, chemical industry, power industry and other occasions where the nominal pressure is PN1.6~16MPa and the working temperature is - 29~550 ℃. It can cut off the fluid and is suitable for full open and full close forms, It is generally not recommended to adjust and throttle, because the imbalance force is too large during adjustment, which will cause severe erosion to the valve core.

Features of electric flange stop valve:
 
1. Compact structure, reasonable design, good rigidity of valve, smooth passage and small flow resistance coefficient.
2. The opening or closing stroke of J941H electric flange stop valve stem is relatively short, and it has a very reliable cutting action.
3. The upper seal seat is designed on the valve cover to make the packing seal more reliable and facilitate the replacement of the packing under the fully open state.
4. J941H electric stop valve can be divided into plane seal and cone seal according to different sealing forms. The sealing surface is made of stainless steel and hard alloy, with long service life.
5. The packing and gasket can be reasonably selected according to the actual working conditions or user requirements, and can be applied to various pressure, temperature and medium working conditions, with reliable sealing and excellent performance.

Operating principle of electric flange stop valve:
 
The opening and closing parts of the electric flange stop valve are plug shaped valve clacks. The sealing surface is flat or conical. The valve lever is rotated by electric thrust. The valve clack moves in a straight line along the center line of the fluid, making the sealing surface of the valve clack closely fit with the sealing surface of the valve seat, and preventing the flow of media. The movement forms of the valve stem include lifting rod type (the valve stem rises and falls, and the hand wheel does not rise and fall), and lifting rotary rod type (the hand wheel rotates with the valve stem to rise and fall, and the nut is located on the valve body). The electric flange stop valve only allows one-way flow of media and has directionality during installation. The structural length of the stop valve is longer than that of the gate valve, and the fluid resistance is large, so the sealing reliability is not strong during long-term operation.
