Introducing an advanced solution for your fluid control needs – the Sanitary EPDM PTFE Compounded Butterfly Valve Liner from Sansheng Fluorine Plastics. Engineered for excellence, this product represents a leap forward in valve technology, combining the resilience of EPDM rubber with the chemical resistance of PTFE to offer unparalleled performance in a variety of industrial settings. The core of our product lies in its innovative construction. A sturdy base of EPDM rubber provides excellent elasticity and temperature resistance, ensuring a tight seal across a wide range of operating conditions. Overlaid with a layer of PTFE, known for its exceptional resistance to corrosive chemicals, our valve sealing ring can withstand exposure to water, oil, gas, bases, and even aggressive acids without degrading. This combination not only enhances the durability and longevity of the liner but also significantly expands its application potential. Our valve liners are available in a broad spectrum of sizes, from DN50 to DN600, making them suitable for a wide variety of piping systems. Whether deployed in the water treatment industry, chemical processing plants, or oil and gas distribution networks, these liners ensure reliable performance and leak-proof operation. The design facilitates easy installation in wafer-type centerline soft-sealing butterfly valves, including pneumatic wafer butterfly valves, enhancing their functionality and efficiency. The color customization option allows for seamless integration into existing systems without compromising on aesthetics. With connection types including wafer and flange ends and compliance with multiple standards such as ANSI, BS, DIN, and JIS, our product is versatile and adaptable to a wide range of international projects. The choice of seat materials – EPDM/FKM + PTFE – coupled with the availability of butterfly valve types, including lug type double half shaft butterfly valves without pins, offers flexibility to meet specific application requirements.



Highlighting innovative features such as the conductive PTFE+EPDM and UHMWPE seat options for centerlined wafer and lug butterfly valves, our product is a testament to cutting-edge engineering and design. It ensures optimal performance in controlling fluid flow, with sizes ranging from 2'' to 24'' to cater to diverse industry needs. At Sansheng Fluorine Plastics, we are committed to providing products that meet the highest quality standards. Our sanitary EPDM PTFE compounded butterfly valve sealing rings are not just components; they are a promise of reliability, efficiency, and excellence in fluid management. Trust us to be your partners in achieving operational success across a multitude of fluid control applications.
