The centerline soft-sealing butterfly valve is a conventional butterfly valve preferred for pipelines. It has a simple structure, a small flow resistance coefficient, and the flow characteristics tend to be linear without retaining debris. It has the advantages of light weight, easy installation and small driving torque. This kind of valve can be used to cut off the medium and adjust the flow of the medium. The driving device can be manual, electric, pneumatic, etc. according to user requirements. Parts made of different materials and sealing rings made of different materials can be used to adapt to different media and working conditions, so as to achieve the best results in cost and performance.

Soft-sealing butterfly valves are suitable for industries such as water supply and drainage, sewage, food, heating, gas, ships, hydropower, metallurgy, energy systems, and textiles with temperatures ≤120°C or ≤150°C and nominal pressures ≤1.6MPa. They are especially suitable for two-way sealing and In situations where the valve body is prone to rust, it can be used as a flow regulating and intercepting medium.
