​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.

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.
