Nylon plate wafer butterfly valve is a common industrial valve. It uses nylon plate as the body material and fixes the valve on the pipeline through a clamping device. Its length is usually around 200mm.

Epoxy coating is a commonly used anti-corrosion measures, wafer butterfly valve can also be treated with epoxy coating. Epoxy coating can effectively prevent the butterfly valve from corrosion and wear during use, and improve the service life of the butterfly valve.

The stainless steel all-PTFE butterfly valve is a valve with excellent performance and corrosion resistance. It is made of stainless steel, with smooth surface, high temperature resistance and corrosion resistance, and can run stably for a long time under harsh working conditions.
