The disc of the wafer butterfly valve is installed in the diameter direction of the pipeline. In the cylindrical channel of the butterfly valve body, the disc-shaped disc rotates around the axis, and the rotation angle is between 0° and 90°, which can play the role of flow regulation. When the disc rotates to 90°, the valve reaches the maximum opening. The wafer butterfly valve is simple in structure, small in size and light in weight, and only consists of a few parts. And it only needs to rotate 90° to open and close quickly, the operation is simple, and the valve has good fluid control characteristics.

Application areas:

1. It is used for gas pipelines in the sulfuric acid industry: the inlet and outlet of the blower in front of the furnace, the inlet and outlet of the relay fan, the series and connecting valve of the electric demister, the inlet and outlet of the S02 main blower, the adjustment of the converter, the inlet and outlet of the preheater, etc. and the use of cut-off gas.

2. It is used in the sulfur incineration, conversion and dry suction sections of the sulfuric acid system. It is the preferred brand of valves for the sulfuric acid plant. It is considered by the majority of users as: good sealing performance, light operation, secondary corrosion, high temperature resistance, operation Convenient, flexible, safe and reliable butterfly valve has been widely used.

3. Also widely used in: SO2, steam, air, gas, ammonia, CO2 gas, oil, water, brine, lye, seawater, nitric acid, hydrochloric acid, sulfuric acid in chemical, petrochemical, smelting, pharmaceutical, food and other industries It is used as a regulating and shut-off device on the pipeline of medium such as phosphoric acid and phosphoric acid.

1. Small and light , and easy installation and mintanance. It can be mounted wherever needed. 2. Compact structure, 90 degree fast switch.3. Miniminzed operating torque, energy saving. 4. Flow curve tending to straight line. Excellent regulation performance. 5. Long service life Standing the test of tens of thousands opening/closing operations. 6. Bubbles-tight sealing with no leakage under the pressure test. 7. Wide selection of materials, applicable forvarious medium.
