Sansheng Fluorine Plastics proudly introduces its flagship product, the Keystone Resilient Butterfly Valve Sealing Ring, a testament to our commitment to quality and efficiency in industrial applications. Engineered with the perfect blend of PTFE (Polytetrafluoroethylene) and EPDM (Ethylene Propylene Diene Monomer), this sealing ring sets the benchmark for durability, resilience, and performance under any condition. Our PTFE butterfly valve seal exemplifies precision manufacturing to ensure unparalleled sealing capabilities. Designed to withstand pressures ranging from PN6 to PN16 and Class 150, it caters to a diverse array of requirements, reinforcing its suitability across various media including water, oil, gas, base oils, and even corrosive acids. The versatility of this product is unmatched, making it an ideal choice for applications in valves and gas systems where uncompromised integrity is crucial. Dimensions are meticulously calibrated, covering port sizes from DN50 to DN600, to accommodate a broad spectrum of piping and valve configurations. The customization doesn't end there; we offer a spectrum of colors to match your specifications, along with a choice between wafer and flange ends for seamless installation. The hardness of the seal can also be customized, providing an adaptive solution that meets your specific operational needs. Whether you require EPDM, NBR (Nitrile Butadiene Rubber), EPR (Ethylene Propylene Rubber), PTFE, NBR, EPDM, FKM (Fluoroelastomer), or FPM (Fluorinated Propylene Monomer) for the seat material, our valve seals are designed to deliver optimal performance and longevity. At Sansheng Fluorine Plastics, we understand the critical role that a reliable butterfly valve plays in the operational efficiency and safety of industrial applications. Our wafer type centerline soft sealing butterfly valve and pneumatic wafer butterfly valve are crafted to offer not just superior performance but also ease of integration into existing systems. Their design is a convergence of innovation and functionality, featuring lug type double half shaft without pin for enhanced durability and maintenance ease.
