Butterfly valve is opened and closed by disc type Reciprocating gyrati Open close and adjust at about 90 degrees A valve for regulating fluid passages.
Butterfly valves are not only simple in structure, small in volume, light in weight, low in material consumption, small in installation size, small in driving moment, simple in operation and fast in operation, but also have good flow regulation function and sealing characteristics.
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-sealed butterfly valves have been widely used in high and low temperature, strong erosion resistance, long life and other industrial fields, so that the technology of butterfly valves has reached a new level.
