In today's dynamic industrial landscape, where precision and durability are paramount, Sansheng Fluorine Plastics leads the way with our top-tier Keystone sanitary butterfly valve seat. Crafted from an innovative compounding of PTFE and EPDM, this product marries the unmatched chemical resistance of PTFE with the elasticity and durability of EPDM. The result is a valve seat that not only stands up to a broad range of operational pressures – from the standard PN6 to the more demanding PN16 and Class 150 – but also excels in a diverse array of media including water, oil, gas, base, oil, and acid. Available in sizes ranging from DN50 to DN600, our valve seats offer versatility for applications in valves and gas systems.



Emphasizing both form and function, the Keystone sanitary butterfly valve seat is designed to cater to a wide spectrum of industry needs. The astounding white and black color scheme not only signifies the purity and strength of the materials used but also allows for customization according to customer requests. This adaptability extends to its connections, offering both wafer and flange ends to suit various assembly requirements. With standards compliance to ANSI, BS, DIN, and JIS, our product assures global applicability and ease of integration into existing systems. At the heart of our product's excellence is its application in the wafer type centerline soft sealing butterfly valve and pneumatic wafer butterfly valve. These valves, integral in controlling the flow of fluids within a system, leverage the unique properties of our valve seats to ensure airtight sealing and long-term reliability. The versatility of our product is further highlighted by its compatibility with various seat materials such as NBR, Rubber, and FKM/FPM, alongside the primary EPDM and PTFE. Whether deploying in high-stress industrial settings or for more routine flow control needs, the Keystone sanitary butterfly valve seat from Sansheng Fluorine Plastics stands as the epitome of innovation, durability, and precision.
