In the complex and demanding world of fluid control and regulation, the performance and reliability of valve components are paramount. Sansheng Fluorine Plastics introduces the cutting-edge Keystone EPDM+PTFE Butterfly Valve Sealing Ring, an innovative solution designed for the sanitary butterfly valve applications. This product represents a fusion of durability, precision, and high-grade material engineering, tailored for businesses seeking unparalleled efficiency in their operations. The Keystone EPDM+PTFE Butterfly Valve Sealing Ring stands as a testament to advanced material technology, combining the robust qualities of EPDM (Ethylene Propylene Diene Monomer) with the unparalleled chemical resistance of PTFE (Polytetrafluoroethylene). This synergy yields a valve sealing ring that is not only hardy against extreme temperatures, ranging from -40℃ to 135℃, but also versatile across a variety of media including water. Its design caters to a broad spectrum of butterfly valves, accommodating sizes from DN50-DN600. The wafer and flange ends connection options further enhance its adaptability to different system requirements.



The application of this valve seal transcends ordinary expectations. Beyond its fundamental role in ensuring a tight seal to prevent leaks, the material composition of the Keystone EPDM+PTFE provides exceptional longevity and minimizes maintenance needs. This is critical in industries where sanitation and cleanliness are paramount, reducing the risk of contamination and ensuring the safe passage of fluids. Whether for use in wafer type centerline soft sealing butterfly valves, pneumatic wafer butterfly valves, or lug type double half shaft butterfly valves without pin, this sealing solution promises dependability and performance. Its black color is not just about aesthetics but signifies the robustness and quality of the material used, ensuring it remains integral to the valve's functionality even in the most demanding conditions. Furthermore, the Keystone EPDM+PTFE Butterfly Valve Sealing Ring is designed with the end user in mind. Its seat options—ranging from EPDM, NBR, EPR, PTFE, to VITON—offer unmatched flexibility, enabling customization to specific operational needs. This adaptability, coupled with its superior sealing properties, makes it an essential component for any butterfly valve, ensuring fluid control processes are smooth, efficient, and reliable. In choosing the Keystone EPDM+PTFE seal for your butterfly valves, you are not just investing in a product but in peace of mind, knowing that your fluid control systems are sealed with the best the industry has to offer.
