In the arena of fluid control and regulation within industrial processes, the significance of a reliable valve sealing mechanism cannot be overstated. Sansheng Fluorine Plastics brings to the forefront a revolutionary product in this domain - the Sanitary EPDM PTFE Compounded Butterfly Valve Sealing Ring. This innovative sealing solution, crafted meticulously with the keyword butterfly keystone at its core, stands as a testament to the company’s commitment to excellence and innovation in facilitating seamless industrial operations.



Diving deeper into the technical prowess of our product, the hybrid composition of PTFE+EPDM combines the resilience and durability of EPDM rubber with the exceptional chemical resistance of PTFE. This synergy results in a sealing solution that is not just white and black in appearance, but also robust across varying pressure gradients including PN16, Class150, and a range from PN6-PN10-PN16 (Class 150). Such versatility ensures that our seals are adept at handling a broad spectrum of media - from water, oil, and gas to base oil and acids, thereby promising a seal that is as versatile as it is reliable. The applicability of our butterfly keystone valve sealing ring spans a diverse range of port sizes from DN50-DN600, making it ideal for an extensive gamut of valve types including wafer type centerline soft sealing butterfly valves and pneumatic wafer butterfly valves. With an option for customization in color to meet the customer's request and designed to facilitate wafer and flange connections, our product meets international standards including ANSI, BS, DIN, and JIS. Moreover, the seating options cater to a wide array of requirements with materials like EPDM, NBR, EPR, PTFE, NBR, Rubber, PTFE/NBR/EPDM/FKM/FPM being available, ensuring that our butterfly keystone valve seals surpass expectations in both performance and durability.
