In the world of fluid control and regulation, the integrity and reliability of valve components are paramount. At Sansheng Fluorine Plastics, we understand the critical nature of these components, particularly when it comes to the heart of butterfly valves - the valve seat. Our premier product, the Sanitary EPDM PTFE Compound Butterfly Valve Liner, stands as a testament to our commitment to excellence and innovation in the field of valve technology. Constructed from a superior compound of PTFE (Polytetrafluoroethylene) and EPDM (Ethylene Propylene Diene Monomer), this valve seat encapsulates the best of both materials, offering exceptional chemical resistance, durability, and resilience across a wide temperature range from -40℃ to 135℃. This unique blend ensures that our valve seats not only withstand harsh environments but also maintain their integrity and sealing capabilities, making them an ideal choice for various media, including water, and for applications across different industries.



Our sanitary EPDM PTFE compound butterfly valve liner is designed to fit seamlessly into butterfly valves, with a size range accommodating DN50-DN600 port sizes.

In addition to its robust material and design, the liner is available in black, offering a sleek and professional appearance that complements any system. Choosing the right valve seat is crucial to ensuring the performance and longevity of your valve assembly.
