In the world of industrial valves, the integrity and reliability of your equipment are paramount. At Sansheng Fluorine Plastics, we understand the critical role that a high-quality valve seat plays in the function and longevity of butterfly valves. That's why we're proud to introduce our top-of-the-line sanitary EPDM PTFE compound butterfly valve liner, specifically designed to meet the demanding standards of bray valve seats.



Our valve liners are meticulously crafted from a superior blend of PTFE and EPDM. This combination not only ensures exceptional chemical resistance but also offers outstanding temperature resilience, ranging from -40℃ to 135℃. This makes our valve seats perfect for a wide variety of media, including water, ensuring reliable operation even in the harshest conditions. The adaptability of our product is further highlighted by its suitability for port sizes ranging from DN50 to DN600, making it a versatile choice for various butterfly valve applications. At the heart of our product's excellence is its application in both wafer type centerline soft sealing butterfly valves and pneumatic wafer butterfly valves. The unique design of our valve liners, black in color, ensures a perfect seal every time, preventing leaks and maintaining the integrity of your systems. The various connection options, including wafer and flange ends, alongside a comprehensive seat selection (EPDM, NBR, EPR, PTFE, NBR, Rubber, PTFE/NBR/EPDM/VITON), provide unparalleled flexibility in valve type configuration. Whether you're in need of a standard butterfly valve, a lug type double half shaft butterfly valve without pin, or a custom solution, our PTFE bonded with EPDM valve seat for centerline butterfly valve sized 2 - 24 inches stands ready to exceed your expectations.
