  •  Electric flange stop valve

Product overview

The electric flange stop valve (j941h) has good strength, stiffness and flow capacity. It is composed of electric actuator and flange stop valve. It receives 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, stiffness and flow capacity, and can be used in various pressure, temperature and medium conditions. It is widely used in the pipeline of environmental protection, petroleum, chemical industry, power industry and other occasions with nominal pressure of pn1.6 ~ 16MPa and working temperature of - 29 ~ 550 ℃. It can cut off the fluid, and is suitable for full opening and full closing, which is generally not built The adjustment force is too large to adjust the valve core.

Features of electric flange stop valve:
 
1. Compact structure, reasonable design, good rigidity of valve, smooth channel and small flow resistance coefficient.
2. J941h electric flange globe valve stem opening or closing stroke is relatively short, and has very reliable cut-off action.
3. The upper seal seat is designed on the valve cover, which makes the packing seal more reliable and convenient for the replacement of the packing in the fully open state.
4. J941h electric stop valve can be divided into plane seal and conical face seal according to different sealing forms. The sealing surface is made of stainless steel and cemented carbide, with long service life.
5. Packing and gasket can be reasonably selected according to actual working conditions or user requirements, and can be applied to various pressure, temperature and medium conditions, with reliable sealing and excellent performance.

Working principle of electric flange stop valve:
 
The opening and closing parts of the electric flange stop valve are plug-shaped disc, and the sealing surface is flat or conical. The valve rod is rotated by electric thrust, and the valve disc moves in a straight line along the center line of the fluid, so that the sealing surface of the valve disc and the sealing surface of the valve seat are closely connected to prevent the medium flow. The movement forms of the valve stem include the lifting rod type (the valve rod rises and falls, and the hand wheel does not rise and fall), and there are also the lifting and rotating rod type (the hand wheel and the valve rod rotate and lift together, and the nut is set on the valve body). The electric flange stop valve only allows one-way flow of medium, and has directionality during installation. The structure length of the stop valve is longer than that of the gate valve. At the same time, the fluid resistance is large, and the sealing reliability is not strong in long-term operation.
