At Sansheng Fluorine Plastics, we are dedicated to delivering solutions that make a real difference in fluid management systems. Our PTFE+EPDM Compound Butterfly Valve Liner stands at the forefront of valve technology, offering an unparalleled blend of durability and performance. Designed for a wide range of applications, including water, oil, gas, base oils, and even harsh acids, this innovative sealing solution meets the rigorous demands of modern industries.



Crafted from a composite material that combines the exceptional chemical resistance of PTFE (Polytetrafluoroethylene) with the elasticity and resilience of EPDM (Ethylene Propylene Diene Monomer), our valve liner ensures a tight seal even under fluctuating temperatures and pressures. This unique combination not only prolongs the life of the butterfly valve but also significantly enhances its reliability in controlling fluid flow. Available in sizes ranging from DN50 to DN600 and compatible with various pressure ratings like PN6, PN10, PN16, and Class 150, our liners accommodate a diverse set of piping requirements and specifications. The ease of installation and maintenance is another highlight of our product. Designed for both wafer and flange connections, the Sansheng PTFE+EPDM Compound Butterfly Valve Liner fits seamlessly into existing systems, minimizing downtime and facilitating quick replacements or upgrades. Whether you're dealing with pneumatic wafer butterfly valves or lug type double half shaft butterfly valves without pins, our liners adapt effortlessly, ensuring optimal performance. Customizable in color and hardness based on customer requirements, we go the extra mile to provide a solution that not only meets but exceeds expectations. At Sansheng, we believe in serving our clients with products that set new benchmarks in quality and innovation.
