Butterfly valve is a kind of valve that uses circular disc as the opening and closing member and rotates to open, close and adjust the fluid passage with the valve stem. The butterfly valve is not only simple in structure, small in size, light in weight, low in material consumption, small in installation size, small in driving torque, easy to operate and fast, and also has good flow regulating function and closed sealing characteristics in large and medium calibers. In the field of low pressure use, butterfly valves are the dominant valve form.

Feature of PVC Butterfly Valve: Disc and seat that touch medium are made from plastic and rubber. Multi-hole ﬁt for different standards connection. Valve is easy to assemble and disassemble to replace damaged parts. Small open and close torque make valve easy to handle. Strong hand lever design make operate easier. Electric and pneumatic actuator mounting are available.
With the application of anti-corrosion synthetic rubber and polytetrafluoroethylene, the performance of the butterfly valve is improved and is satisfied by different working conditions. In the past ten years, metal sealing butterfly valves have developed rapidly. With the application of high temperature resistance, low temperature resistance, strong corrosion resistance, strong erosion resistance and high strength alloy materials in butterfly valves, metal sealing butterfly valves are exposed to high temperature, low temperature and strong erosion. It is widely used under various working conditions and partially replaces the globe valve, gate valve and ball valve.
Structural features Butterfly valve has the characteristics of simple structure, small size, light weight, material consumption, small installation size, quick switch, 90° reciprocating rotation, small driving torque, etc. It is used to cut off, connect and adjust the medium in the pipeline. Has good fluid control characteristics and closes sealing performance.Butterfly valve is either can be a shut-off valve or a control valve, the open and close action is controlled by rotarying the round disc, it is mainly for cutting off the pipeline. Plastic butterfly valve is mainly used for corrosive liquid, body and disc material is made by PVC, CPVC, PVDF, PP. seat material is usually made by EPDM, NR, NBR, VITON and PTFE.

Butterfly valve is mainly used in industrial water treatment, fish farm, mining, steel, chemical and other industries. The company's butterfly valve products include: PVC butterfly valve, CPVC butterfly valve, PVDF butterfly valve, PP butterfly valve, PPH butterfly valve, PTFE lined butterfly valve and other products. PVDF Butterfly Valve is made by PVDF body with seat EPDM or Viton, lug type or wafer connection as per standard DIN PN10, ANSI CL150, JIS10K. Model RPV121A is lever type PP Butterfly Valve. Size from 2" to 8", working pressure PN10, work temperature up to 145 degree. PVDF Butterfly Valve is most suitable for chemical industrial, semi conduct industrial and other strong acids.
