In the realm of industrial valve applications, ensuring the integrity and reliability of sealing components is paramount. Sansheng Fluorine Plastics stands at the forefront of this challenge with its state-of-the-art Sanitary EPDM PTFE Compounded Butterfly Valve Sealing Ring, a hallmark of innovation in the butterfly keystone sealing solutions sector. This product represents a fusion of quality, reliability, and performance, tailored to meet the rigorous demands of modern industrial applications involving water, oil, gas, base oil, and acids.



Crafted with an expert blend of PTFE and EPDM, our sealing rings emerge as a composite of white and black materials, symbolizing the integration of strength (owing to PTFE's robust chemical resistance) and elasticity (thanks to EPDM's durable nature). This combination ensures a long-lasting seal that stands up to various pressure ranges, including PN16, Class150, and PN6-PN10-PN16 (Class 150), making it versatile across different settings. Suitable for port sizes ranging from DN50 to DN600, our seals offer unparalleled adaptability and compatibility with diverse valve types, including wafer type centerline soft sealing butterfly valves and pneumatic wafer butterfly valves. The Sansheng Fluorine Plastics' butterfly keystone sealing ring is designed with the end-user in mind. Color customization is available upon request, allowing our clients to match the product with their specific equipment or branding requirements. The connection method is equally versatile, featuring both wafer and flange ends to suit a variety of installation contexts. Upholding standards such as ANSI, BS, DIN, and JIS, we ensure our products meet the global benchmarks of quality and performance. Whether you are in need of a solution for a butterfly valve, lug type double half shaft butterfly valve without pin, or seeking a custom color PTFE valve seat, our innovative PTFE-coated EPDM valve seat for resilient seat butterfly valves ranging from 2''-24'' sets new industry standards.
