In the realm of industrial fluid management, the integrity and reliability of valve components are paramount. Sansheng Fluorine Plastics leads the way with its innovative sanitary EPDM PTFE compound butterfly valve liner, a pinnacle of modern engineering designed to offer unmatched performance in diverse applications. This advanced sealing solution is specifically crafted to cater to the rigorous demands of butterfly valve systems, ensuring a leak-proof, robust seal that stands the test of time and pressure.



At the heart of our product is the unique combination of PTFE and EPDM, materials renowned for their exceptional chemical resistance, durability, and operational reliability across a wide temperature range from -40℃ to 135℃. This blend not only capitalizes on the strengths of both materials – the unparalleled chemical resistance and slick surface of PTFE, and the elastic and weather-resistant properties of EPDM – but also addresses the need for a versatile sealing solution capable of handling various media, including water, under differing environmental conditions. Designed for wafer and flange connections with port sizes ranging from DN50 to DN600, our compound butterfly valve sealing rings are the ideal choice for applications requiring meticulous control over fluid flow. The product lineup includes options suited for different applications, from wafer type centerline soft sealing butterfly valves to pneumatic wafer butterfly valves, and lug type double half shaft butterfly valves without pin. With a black coloration that signifies its robustness and quality, each sealing ring is crafted to provide an impenetrable barrier against leaks, ensuring efficient operation of your butterfly valve assemblies. Sansheng’s commitment to innovation and quality makes our compound butterfly valve sealing rings the definitive choice for industries looking to enhance their fluid control systems with components that offer reliability, longevity, and optimal performance.
