Product Description

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.
Compared with the Gate valve, the wafer butterfly valve has the characteristics of simple structure, small volume and light weight.
It consists of only 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.
When the butterfly valve is in the fully open position, the thickness of the butterfly plate is the only resistance when the medium flows through the valve body, so the pressure drop generated by the valve is very small, so it has better flow control characteristics. Butterfly valve has two types of sealing type: elastic soft seal and metal seal. Elastic soft sealing valve, the sealing ring can be embedded on the valve body or attached to the periphery of the disc.
Valves with metal seals generally have a longer life than those with elastic seals, but it is difficult to achieve complete sealing. Metal seals can adapt to higher operating temperatures, while elastic soft seals have the defect of being limited by temperature.
When the project is used and installed, the double-headed butterfly valve is connected between the two pipeline flanges with stud bolts, and the flanges at both ends of the valve are connected to the pipeline flange with bolts.
The wafer butterfly valve has good sealing performance, light operation, secondary corrosion, high temperature resistance, convenient operation, flexibility, safe and reliable use, and has been widely used.
Widely used in cooling water systems of petroleum, gas, chemical, water treatment, thermal power stations, and SO2, steam, air, gas, ammonia, CO2, oil, water in chemical, petrochemical, smelting, pharmaceutical, food and Other industries , Brine, lye, seawater, nitric acid, hydrochloric acid, sulfuric acid, phosphoric acid and other media pipelines are used as adjustment and interception devices.
