​Sanitary welded butterfly valve adopts butt-welding connection, overcoming the shortcomings of flange, pipe thread, trapezoidal thread and other traditional connections in our country, with simple structure, beautiful modeling, quick assembly and disassembly, rapid switching, flexible operation, low fluid resistance, the use of an all reliable, etc., and can be used with a variety of actuators operation. All steel parts of the valve are made of acid-resistant stainless steel, and the seals are made of food silicone rubber or PTFE, which is in line with food hygiene standards, and is widely used in the industries of food, brewing, beverage, dairy products, fine chemicals, pharmaceutical and biological engineering.

the butterfly plate of the clamping butterfly valve is installed in the diameter direction of the pipe. In the butterfly valve body cylindrical channel, the disc disc around the axis rotation, rotation Angle is between 0°-90°, rotation to 90°, the valve is fully open. The valve is generally installed horizontally. The clamping butterfly valve is simple in structure, small in size, light in weight, and only consists of a few parts. And only need to rotate 90° can be quickly opened and closed, simple operation, 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 small, so it has better flow control characteristics. The butterfly valve has two sealing types: the shell seal and the metal seal. Flexible seal valve, seal ring can be inlaid on the body or attached to the disc around.

Butterfly valves can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, mud, oil, liquid metal and radioactive media. It mainly plays the role of cutting and throttling on the pipeline. The butterfly valve opening and closing part 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.
