In the realm of industrial valve solutions, the importance of choosing the right seal cannot be overstated. Sansheng Fluorine Plastics brings to the forefront an innovative sealing solution with its EPDM+PTFE butterfly valve sealing ring. This product has been meticulously designed to cater to a broad spectrum of industrial applications, setting a benchmark in reliability and performance. The material composition of the sealing ring combines the best attributes of PolyTetraFluoroEthylene (PTFE) and Ethylene Propylene Diene Monomer (EPDM). PTFE is renowned for its exceptional chemical resistance and low friction properties, making it ideal for handling a wide range of media, including water. On the other hand, EPDM adds to the durability by offering unparalleled resistance to weathering, ozone, and steam, along with excellent temperature resilience ranging from -40℃ to 135℃. This synergistic blend ensures that the sealing ring stands up to the rigorous demands of various industrial environments, significantly reducing maintenance needs and downtime.



The application of this EPDM+PTFE compound extends predominantly to butterfly valves, where it acts as a superior sealing solution. Available in sizes ranging from DN50 to DN600, it is compatible with both wafer and flange connection types. Whether you're dealing with a Wafer Type Centerline Soft Sealing Butterfly Valve or a Lug Type Double Half Shaft Butterfly Valve Without Pin, this sealing ring promises a leak-proof operation. Its black color marks a standard in the industry, while the option of customization in terms of material—ranging from NBR and EPR to VITON—allows for tailored solutions to meet specific operational requirements. Sansheng Fluorine Plastics’ dedication to innovation and quality is evident in this EPDM+PTFE butterfly valve sealing ring. Engineered for longevity and performance, it represents not just a component, but a commitment to operational excellence. Whether for water treatment plants, food and beverage production, or chemical processing facilities, this sealing ring ensures that your butterfly valves operate efficiently, safely, and without interruption.
