In the demanding world of fluid control and regulation, the integrity of valve sealing components plays a pivotal role in maintaining operational efficiency and environmental safety. Sansheng Fluorine Plastics takes pride in introducing its state-of-the-art Keystone Resilient Butterfly Valve Sealing Ring, innovatively engineered with an EPDM+PTFE compound. This cutting-edge solution caters to a broad spectrum of industrial applications, offering unmatched reliability and performance.



Crafted from the synergistic blend of Ethylene Propylene Diene Monomer (EPDM) and Polytetrafluoroethylene (PTFE), our valve liner stands as a paradigm of durability and chemical resistance. The unique properties of EPDM, renowned for its excellent resistance to wear, weathering, and ozone, combined with the unparalleled chemical inertness of PTFE, ensure your valve operates flawlessly under varying pressures (PN6-PN10-PN16, Class 150) and diverse media including water, oil, gas, base oils, and acids. This synthesis not only elevates the sealing ring's resilience but also significantly extends its service life in harsh industrial environments. Our Keystone Resilient Butterfly Valve Sealing Ring, available for valve sizes ranging from DN50 to DN600, is designed to cater to an extensive array of applications – may it be valves, gas, or other fluid control systems. It's customizable in color and hardness according to your specific requirements, ensuring a perfect fit for your operational needs. The versatility of the seal is further enhanced by its compatibility with various connection types, including Wafer and Flange Ends, making it a universal solution for your butterfly valve applications. Whether it's a Wafer Type Centerline Soft Sealing Butterfly Valve or a pneumatic variant you're employing, our EPDM+PTFE compounded liner guarantees superior performance, safety, and reliability, thereby optimizing your operational efficiency and minimizing maintenance costs.
