In the realm of valve technology, the durability and efficiency of valve components play pivotal roles in ensuring system integrity and fluid control management. Sansheng Fluorine Plastics introduces its premier product - the Sanitary EPDM PTFE Compound Butterfly Valve Liner, a marvel in the valve manufacturing industry that sets a new standard for reliability and performance. Crafted from a robust combination of PTFE (Polytetrafluoroethylene) and EPDM (Ethylene Propylene Diene Monomer), this valve liner champions unmatched resilience against a wide temperature range of -40℃ to 135℃. This broad temperature spectrum makes it an ideal choice for applications involving water as the primary medium, with port sizes available from DN50 to DN600, catering to a vast array of installation requirements. The application of this ground-breaking liner extends to butterfly valves, including wafer type centerline soft sealing butterfly valves and pneumatic wafer butterfly valves. Its remarkable material composition, black in color, allows for a seamless integration into existing systems without the compromise of aesthetic uniformity. The connection facilitation is meticulously designed, supporting both wafer and flange ends, ensuring a secure and leak-proof operation. Moreover, the seat options available with this liner are varied and include EPDM, NBR, EPR, PTFE, NBR, Rubber, PTFE/NBR/EPDM/VITON, accommodating a range of system requirements and specifications. The valve types compatible with this liner are extensive as well, encompassing butterfly valve and lug type double half shaft butterfly valve without pin, illustrating the versatility and adaptability of the product in different operational setups.



At the core of this product is a PTFE bonded with EPDM valve seat designed specifically for centerline butterfly valves ranging from 2 to 24 inches. This unique blend of PTFE and EPDM not only promises an enhanced lifespan due to its chemical resistance and flexibility but also guarantees a high-performance seal that minimizes maintenance needs and operational downtime. In conclusion, Sansheng Fluorine Plastics' Sanitary EPDM PTFE Compound Butterfly Valve Liner embodies the pinnacle of valve sealing technology. It not only meets the rigorous demands of modern fluid control systems but exceeds expectations in reliability, adaptability, and performance. Whether for industrial, commercial, or residential applications, this butterfly valve liner stands as a testament to innovative engineering, ensuring optimal functionality and efficiency in any setting.
