In the world of valve manufacturing and maintenance, the significance of a high-caliber seal cannot be overstated. At Sansheng Fluorine Plastics, we have dedicated our expertise to the development of a solution that not only meets but exceeds industry standards—the Sanitary EPDM PTFE Compounded Butterfly Valve Sealing Ring. This innovative product stands at the intersection of durability and flexibility, offering an unparalleled sealing solution for a wide range of applications.



Crafted from a strategic blend of PTFE and EPDM, our sealing ring exhibits outstanding properties that make it particularly suited for use in valves that manage water, oil, gas, base oil, and acid media. The PTFE component of the ring contributes its well-known resistance to chemical corrosion and extreme temperatures, while EPDM lends its excellent resilience under pressure and against weathering. This harmonious combination results in a white and black sealing ring capable of operating effectively within a pressure range of PN16, Class 150, and PN6-PN10-PN16 (Class 150), catering to port sizes from DN50 to DN600. The application of our sealing ring extends beyond simple utility; it is engineered to elevate the performance of wafer type centerline soft sealing butterfly valves and pneumatic wafer butterfly valves. Compatibility with various valve types, including butterfly valves and lug type double half shaft butterfly valves without pin, underscores the versatility of our product. The connection types supported—wafer and flange ends—along with adherence to international standards such as ANSI, BS, DIN, and JIS, assure its adaptability and applicability in global markets. Users have the liberty to request custom colors, ensuring that the aesthetic requirements of any system are met without compromise on functionality. With options including EPDM, NBR, EPR, PTFE, and more for the seat material, our EPDM butterfly valve seal is customizable to meet diverse industrial needs, making it a paramount choice for those in pursuit of reliability and excellence in their valve sealing solutions.
