In the realm of fluid control and management, the importance of high-quality components cannot be overstated. Among these, the Keystone resilient butterfly valve sealing ring stands out as a pivotal element, particularly in applications requiring sanitary conditions. Sansheng Fluorine Plastics, a renowned name in the industry, introduces its cutting-edge solution for businesses seeking optimal performance and reliability: the PTFE Coated EPDM Valve Seat, specially designed for sanitary butterfly valve seals. Crafted with meticulous attention to detail, this sealing solution combines the resilience and flexibility of EPDM with the chemical resistance and non-stick properties of PTFE. This synergy results in a seal that not only ensures tight shut-off and excellent flow control but also withstands the rigors of various media, including water, oil, gas, basic oils, and acids. Available in sizes ranging from DN50 to DN600 (2 inches to 24 inches), our valve seats cater to a broad spectrum of applications, from the food and beverage industry to pharmaceuticals and beyond.



The design of our sanitary butterfly valve seals aligns with the highest standards for hygiene and cleanliness. The wafer-type centerline and soft-sealing butterfly valve, available in both pneumatic and manual variations, offer unparalleled ease of operation and maintenance. The choice of materials—PTFE+EPDM—ensures compatibility with a wide range of operating pressures (PN6 to PN16, Class 150) and temperatures, making it an ideal choice for demanding environments. Additionally, customers have the flexibility to customize the color, hardness, and connection type (wafer or flange ends), aligning with specific system requirements and ensuring a seamless integration into existing setups. Sansheng Fluorine Plastics is committed to delivering products that not only meet but exceed industry standards for performance and reliability. Our sanitary butterfly valve seals are a testament to this commitment, providing businesses with a durable, efficient, and hygienic solution for fluid control. Whether your application involves water treatment, chemical processing, or food and beverage production, our valve seals offer the reliability and performance you need to maintain optimal operations.
