In the world of industrial valve technology, the need for components that offer both resilience and precision is paramount. Sansheng Fluorine Plastics understands this imperative and introduces the DN40-DN500 Compound Butterfly Valve Seal Ring, engineered with a groundbreaking Bray EPDM+PTFE butterfly valve liner. This product is the epitome of innovation, marrying the flexibility of EPDM with the chemical resistance of PTFE, creating a seal ring unmatched in performance and reliability.



Our seal ring stands as a testament to our commitment to quality and performance. The material composition of PTFE+FKM ensures that each valve liner can withstand pressures ranging from PN6 to PN16 and Class 150, making it suitable for a diverse range of applications including water, oil, gas, base oil, and acids. The versatility of our product is further enhanced by its compatibility with port sizes from DN50 to DN600, catering to a broad spectrum of industrial requirements. Furthermore, the application of our wafer type centerline soft sealing butterfly valve, including the pneumatic wafer butterfly valve variant, underscores our dedication to providing solutions that cater to the dynamic needs of valve and gas applications. With a variety of colors upon customer request and connections including wafer and flange ends, our valves are designed to seamlessly integrate into existing systems. Adherence to international standards such as ANSI, BS, DIN, and JIS not only reinforces the quality of our offering but also assures global applicability. The seat options available - EPDM/NBR/EPR/PTFE, NBR, Rubber, PTFE/NBR/EPDM/FKM/FPM - illustrate our commitment to customization and ensuring that each client receives a solution tailored to their specific operational needs. Our valves, whether you opt for the butterfly valve or the lug type double half shaft butterfly valve without pin, are characterized by their customizable hardness, highlighting our flexibility in catering to unique operational requirements.
