Sansheng Fluorine Plastics introduces its groundbreaking solution for industrial fluid control - the EPDM+PTFE compounded butterfly valve liner. This innovative product merges the resilience and flexibility of EPDM rubber with the unparalleled chemical resistance of PTFE, offering a high-performance seal that ensures efficient and reliable operation across a wide range of applications. Crafted for excellence, our EPDM+PTFE butterfly valve seals are designed to fit seamlessly within wafer and lug type butterfly valves, ranging from DN50 to DN600 in port size. These seals are particularly engineered to withstand the demanding conditions found in water, oil, gas, base oils, and even corrosive acids, making them a versatile solution for numerous industries, including petrochemical, water treatment, and manufacturing sectors. The architecture of our butterfly valve liner is a testament to advanced engineering. Featuring a white PTFE layer bonded to a black EPDM core, the liner is further reinforced with a rigid phenolic ring along its perimeter. This robust construction not only enhances the liner's mechanical strength but also ensures a leak-proof seal, reducing maintenance costs and downtime. The adaptability of our valve seal is evident in its compatibility with various standards, including ANSI, BS, DIN, and JIS, allowing for seamless integration into existing systems. Our product, the Wafer Type Centerline Soft Sealing Butterfly Valve, also known as the pneumatic Wafer Butterfly Valve, is customizable in color upon request, catering to the specific aesthetic requirements of our clients. The connection types offered, wafer and flange ends, ensure that installation is straightforward and secure. With seat options including EPDM/FKM+PTFE, our butterfly valve caters to a diverse range of operational conditions, providing a flexible solution that does not compromise on quality or performance.



Highlighting the superior characteristics of our EPDM+PTFE butterfly valve seal is its exceptional durability and resilience. The unique combination of EPDM and PTFE not only withstands a broad spectrum of chemicals but also endures high temperatures and pressures, making it an indispensable asset in critical applications. This dual-material approach ensures that the valve maintains a tight seal, effectively controlling the flow of media and preventing leaks. In summary, Sansheng Fluorine Plastics' EPDM+PTFE compounded butterfly valve liner represents a leap forward in valve sealing technology. Offering remarkable chemical resistance, durability, and flexibility, it stands as an ideal choice for industries seeking reliable fluid control solutions. With our commitment to quality and innovation, we are proud to present a product that meets the rigorous demands of modern industrial operations, ensuring performance, safety, and efficiency.
