Product Introduction

A wafer PTFE seat butterfly valve is a type of butterfly valve that uses a wafer-style body design with a polytetrafluoroethylene (PTFE) seat. This valve is used to regulate or control the flow of various types of liquids, gases, and slurries in a variety of industries, including chemical processing, water treatment, and food and beverage production. The PTFE seat provides excellent chemical resistance, high-temperature tolerance, and low friction, making it an ideal material for use in harsh environments with corrosive or abrasive substances. The wafer design allows for easy installation and removal of the valve, and the butterfly disc provides a low-profile design that minimizes turbulence and pressure drop in the pipeline.

Advantages of wesdom butterfly valve!

  • The thickness of valve body wall is up to standard

    The valve body wall thickness meets the requirement of GB 26640, the thickness is up to the standard, and the pressure strength is guaranteed.

  • Valve body/valve plate is made of QT450-10 material

    Valve body valve plate is made of qt450-10 material with spheroidization rate above grade 3, tensile strength of 450Mpa and elongation of >10%.

  • Good sealing and long service life of  valve seat

    The valve seat is made of imported rubber material, with more than 50% rubber content; Elongation at break greater than 350%, valve sealingreliable, long


  • Soft back with wide side seat

    Soft backrest wide side valve seat, is advantageous to the valve installation, in the pipeline and flange boss contact surface is wide, sealing performance

    is reliable. Life is longer than a hard back. And easy to remove and replace.

  • No pin structure to avoid corrosion

    Butterfly plate and valve shaft adopt through shaft without pin structure to avoid leakage caused by hole mounting pin and accelerated corrosion caused

    by coating damage.

  • Valve body is sprayed with Aksu epoxy powerd

    The valve body is sprayed with world-renowned Aksu epoxy resin powder, which has stronger adhesion and better environmental tolerance after melting and curing.
