Information

Electric louver valves rely on an external power supply to control the rotation opening and closing of each valve plate by an electric drive device. The valve plate realizes the opening and closing state at any angle, such as fully open, half open, or closed, to control the flow of flue gas in the pipeline. To achieve the purpose of adjusting or opening and closing the flue gas circulation in the pipe. The valve body and valve plate of the electric louver valve are welded from high-quality stainless steel plates, with simple structure, small flow resistance, light weight, flexible rotation and long service life.

When installing the electric louver valve, you must check whether there is dirt in the electric louver valve, and then check whether there is any dirt on the flange surface. After cleaning, place the graphite packing flat on the inside of the flange bolt hole of the electric butterfly valve. The joints of the graphite packing must be placed crosswise. The flange is placed flat on the graphite packing. The bolt passes through the flange on the valve body from one side of the flange. Then put the flat washer and spring washer inside the bolt to check the graphite Whether the packing is placed properly, it must not be exposed to the inside of the valve body, it must be in the upper and lower flanges or there may be air leakage, and the nuts are installed lightly. After each nut is installed, pre-tighten diagonally once, and all pre-tighten once , When pre-tightening, there must be no light or heavy. After the valve is installed in the pipeline, all bolts are tightened again.

Attention must be paid when installing, the valve shaft on the electric shutter valve must be in a horizontal position. Electric louver valve is used in conjunction with electric actuator. It has the characteristics of small opening and closing torque, sensitive action, reliable performance and large caliber. The performance indicators of electric shutter valves produced by Johnson Machinery Co., Ltd. meet industry standards and are of reliable quality. They are widely used in metallurgy, building materials, electric power, petrochemical, light industry and other sectors.
