Shanghai Liangda Valve Factory Butterfly Valve Butterfly Valve Principle Butterfly Valve Standard Butterfly Valve Features Butterfly Valve Function Butterfly Valve Size Butterfly Valve Price Butterfly Valve Overview Butterfly valve is a kind of valve that uses circular disc as the opening and closing member and rotates to open, close and adjust the fluid passage with the valve stem. The butterfly valve is not only simple in structure, small in size, light in weight, low in material consumption, small in installation size, small in driving torque, easy to operate and fast, and also has good flow regulating function and closed sealing characteristics in large and medium calibers. In the field of low pressure use, butterfly valves are the dominant valve form.
With the application of anti-corrosion synthetic rubber and polytetrafluoroethylene, the performance of the butterfly valve is improved and is satisfied by different working conditions. In the past ten years, metal sealing butterfly valves have developed rapidly. With the application of high temperature resistance, low temperature resistance, strong corrosion resistance, strong erosion resistance and high strength alloy materials in butterfly valves, metal sealing butterfly valves are exposed to high temperature, low temperature and strong erosion. It is widely used under various working conditions and partially replaces the globe valve, gate valve and ball valve.
Structural features Butterfly valve has the characteristics of simple structure, small size, light weight, material consumption, small installation size, quick switch, 90° reciprocating rotation, small driving torque, etc. It is used to cut off, connect and adjust the medium in the pipeline. Has good fluid control characteristics and closes sealing performance.
