Introducing Sansheng Fluoroplastics' premiere solution for your valve sealing needs: our cutting-edge Sanitary EPDM PTFE Compound Butterfly Valve Liner. This product is engineered with precision to cater to the demanding environments of fluid control systems. Combining the resilience of PTFE (Polytetrafluoroethylene) with the flexibility of EPDM (Ethylene Propylene Diene Monomer), we have crafted a valve seat that stands unmatched in both performance and durability.



Our butterfly valve liner is expertly designed to withstand extreme temperature ranges from -40°C to 135°C, ensuring reliable operation in various industrial applications. Whether it's for water media or other fluids, the adaptability of our valve liner to DN50-DN600 port sizes makes it a versatile choice for a broad range of butterfly valves, including wafer type centerline and pneumatic wafer butterfly valves. The black color of the liner signifies not just a standard design aspect but a commitment to providing a product that maintains its integrity and performance over time. The fusion of PTFE and EPDM materials in our butterfly valve seat offers the best of both worlds - the superior chemical resistance characteristic of PTFE and the excellent weather and ozone resistance of EPDM. This combination ensures that our valve seat remains effective in sealing, reducing the risk of leaks and enhancing the lifespan of your butterfly valves. Available in various seat options such as EPDM, NBR, EPR, PTFE, and VITON, our product caters to different requirements and specifications, setting a new standard in valve seat technology. Whether you're in need of a wafer, flange end connection, or a specific valve type like the lug type double half shaft butterfly valve without pin, Sansheng Fluoroplastics has got you covered. Embrace the innovation of a PTFE bonded with EPDM Valve Seat for Centerline Butterfly Valves ranging from 2 to 24 inches and revolutionize the efficiency of your fluid control systems today.
