Product Details

Resilient Seated Butterfly Valve



Brief introduction

Flange soft sealing butterfly valve is suitable for water supply and drainage, sewage, food, heating, gas, shipping, water and electricity, metallurgy, energy system, textile and other industries with temperature ≤120℃ or ≤150℃ and nominal pressure ≤1.6MPa, especially suitable for two-way For occasions where the seal and valve body are prone to rust, it is used as a flow adjustment and interception medium.

Valves with metal seals generally have a longer life than valves with elastic seals, but it is difficult to achieve a complete seal. Metal seals can adapt to higher operating temperatures, while elastic seals have the defect of being limited by temperature. If the butterfly valve is required to be used as flow control, the main thing is to select the correct size and type of the valve. The structure principle of the butterfly valve is especially suitable for making large diameter valves. Butterfly valves are not only widely used in oil, gas, chemical, water treatment and other general industries, but also used in cooling water systems of thermal power stations. Commonly used butterfly valves include wafer butterfly valves and flange butterfly valves. Wafer type butterfly valve uses double-head bolts to connect the valve between two pipe flanges. Flange type butterfly valve has flanges on the valve, and the two ends of the valve are flanged to the pipe flanges with bolts. When in the fully open position, the thickness of the butterfly plate is the resistance when the medium flows through the valve body. Therefore, the pressure generated by the valve will be small, and it is estimated that it has better flow control characteristics. The butterfly valve has two sealing types: elastic seal and metal seal. Elastic sealing valve, the sealing ring can be inlaid on the valve body or attached to the periphery of the butterfly plate.  Valves with metal seals generally have a longer life than valves with elastic seals, but it is difficult to achieve a complete seal. Metal seals can adapt to higher operating temperatures, while elastic seals have the defect of being limited by temperature.
