Superior Keystone EPDM+PTFE Butterfly Valve Liner | DN40-DN500
In the evolving landscape of industrial applications, having reliable components that can withstand demanding conditions is paramount. At Sansheng Fluorine Plastics, we recognize the critical role that valve seals play in the operational integrity of fluid control systems. The DN40-DN500 compound butterfly valve seal ring, featuring an exceptional blend of EPDM (Ethylene Propylene Diene Monomer) and PTFE (Polytetrafluoroethylene) materials, stands out as a keystone product in our extensive range of valve sealing solutions. This innovative hybrid design not only guarantees superior sealing capabilities but also ensures longevity and resilience across a diverse array of environments and applications.
Crafted with precision, our keystone EPDM+PTFE butterfly valve liner is engineered to meet the specific requirements of varied industrial applications, including water, oil, gas, base oils, and even aggressive acid mediums. Compatible with port sizes ranging from DN50 to DN600, our seal rings cater to an extensive range of butterfly valves including wafer type centerline soft sealing, pneumatic wafer, lug type double half shaft without pin, and more. The utilization of both PTFE and FKM in our products provides an unrivaled balance of chemical resistance and flexibility, ensuring a tight, leak-proof seal under a wide spectrum of pressure conditions — from PN6 to PN16 (Class 150), making it the ideal choice for applications demanding the highest levels of reliability and efficiency. Moreover, our commitment to customization sets us apart. We understand that no two applications are the same, which is why we offer the option to tailor the hardness, color, and specific material composition (such as NBR, EPDM, EPR, FKM, and PTFE combinations) to meet our customers' unique requirements. Whether you're dealing with high-pressure systems, corrosive materials, or extreme temperatures, our keystone EPDM+PTFE butterfly valve liners are designed to deliver unmatched performance and durability. With standards compliance to ANSI, BS, DIN, and JIS, and options for wafer or flange-end connections, our seal rings provide a versatile and reliable solution for ensuring the integrity and efficiency of your valve systems.
