Product Description
With simple structure, light weight, quick opening speed, pneumatic wafer switch butterfly valve consists of the piston type cylinder and the wafer type butterfly valve, and the spring return type valve can support automatic reposition function (air to open and close) when the air and power were cut off. This product is widely applied in the industrial pipeline fields of metallurgy, environmental protection, water treatment, petrochemical, power.

This butterfly valve adopts polytetrafluoroethylene (FEP) as anti-corrosion lining material which has very superior anti-corrosion and abrasion resistance. The unique structure of upper lip type elastic seal lining well extends service life of the product.

This product with high chemical stability is widely used in various piping of liquid, gas including steam, especially suitable for strong corrosive medium such as sulfuric acid, hydrofluoric acid, phosphorus, chlorine, alkali, aqua regia and so on.
