Functions and advantages of flange soft seat expansion butterfly valve

Flange soft seat expansion butterfly valve is mainly used in petroleum, chemical, food, medicine, textile, papermaking, electric power.

Water supply and drainage, gas pipeline, play the role of regulating the flow and closing the medium, with the function of compensating for pipeline expansion and contraction.

Advantages of flange soft seat expansion butterfly valve: 1. The sealing performance is reliable, and the sealing surface is made of soft materials, which can effectively prevent leakage. 2. The valve has a simple structure, small size, light weight, and is easy to install and maintain. 3. The valve has a good flow adjustment performance and a large flow coefficient. 4. The opening and closing torque is small, and the operation is labor-saving. 5. The valve can be used in various media such as water, steam, oil, gas, etc.

Flange soft seat expansion butterfly valve, the structure length can be expanded and contracted within a certain range.

not only facilitates the assembly and disassembly of the valve

The translation is: "but also relieves the pipeline stress and protects the valve while centrally installing the butterfly valve and the expansion device in a more compact space."

Usually, this kind of valve does not need special maintenance, only need to regularly observe the expansion whether there is leakage and pull off and so on.
