In the realm of industrial valve applications, ensuring a secure and durable seal is paramount for maintaining system integrity and operational efficiency. Sansheng Fluorine Plastics presents its flagship solution, the Keystone Resilient Butterfly Valve Sealing Ring, crafted from a superior combination of PTFE and EPDM materials. This innovative teflon butterfly valve liner sets a new benchmark in sealing technology, offering unmatched performance and reliability.



Constructed with the user's needs in mind, our valve liner is designed to withstand pressures ranging from PN6 to PN16 and Class 150, catering to a broad spectrum of industrial requirements. The versatility of the material composition, combining the robustness of PTFE with the flexibility of EPDM, ensures our sealing ring delivers exceptional functionality across a diverse range of media, including water, oil, gas, base oils, and even corrosive acids. This adaptability makes it an ideal choice for various applications, from valves and gas systems to complex industrial setups requiring precise chemical resistance and mechanical durability. Our product portfolio extends from DN50 to DN600 port sizes, accommodating an extensive array of pipeline dimensions and configurations. Each sealing ring is meticulously engineered for wafer or flange end connections, providing a seamless and secure fit to virtually any valve, gas, or pneumatic wafer butterfly valve system. Clients have the freedom to customize the color, hardness, and seat materials (including options such as EPDM, NBR, EPR, and FKM/FPM) to meet their specific operational requirements. The result is a highly resilient, teflon-coated EPDM valve seat that ensures peak performance, reduced maintenance needs, and extended service life, solidifying its place as a keystone in the future of resilient butterfly valve technology.
