The butterfly valve, also called the flap valve, is a valve with a simple structure. The opening and closing part of the butterfly valve is a disc-shaped butterfly plate, which rotates around its own axis in the valve body to achieve the purpose of opening and closing or adjustment.
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, simple and fast in operation, but also has good flow regulation and closing and sealing characteristics at the same time. It has been developed in the past ten years. One of the fastest valve varieties.
Butterfly valves are widely used. Butterfly valves can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, mud, oil, and liquid metal. It mainly plays the role of cutting off and throttling on the pipeline.
The variety and quantity of butterfly valves continue to expand, and are developing towards high temperature, high pressure, large diameter, and high sealing. Now butterfly valves have long service life, excellent adjustment characteristics, and one valve with multiple functions. Its reliability and other performance indicators have reached a high level.
Triple offset butterfly valve is a valve in which the shaft center of the valve stem deviates from the center of the disc and the center of the body at the same time, and the rotation axis of the valve seat has a certain angle with the axis of the valve body channel. The Triple offset butterfly valve produced by Milestone Valve Co. Ltd. is widely used in metallurgy, electric power, petrochemical, and water supply and drainage industrial pipelines with a medium temperature of 425℃ or less. The materials are divided into: cast iron, cast steel, and stainless steel.

The elastic sealing ring has three eccentric contact with the butterfly plate, which realizes the effect of separating the sealing surface at the moment of opening and sealing at the moment of closing, so as to prolong the service life and achieve the best sealing performance. Therefore, wave type hard seal butterfly valve is widely used in metallurgy, electric power, petroleum, chemical industry, air, gas, combustible gas, water supply and drainage and other corrosive medium pipelines with medium temperature ≤ 550 ℃. Wafer Type Hard Seal Butterfly Valve is the best device to regulate flow and cut off fluid.
