In the realm of industrial valve manufacturing, the need for components that ensure utmost reliability, durability, and compliance with stringent sanitary standards is paramount. Sansheng Fluorine Plastics introduces its flagship product, the DN40-DN500 Compound Butterfly Valve Seal Ring, designed to meet these critical requirements. This product stands out as a pinnacle of innovation, combining the resilience and chemical inertness of PTFE with the elasticity and strength of FKM, embodying the term "sanitary compound butterfly valve liner" in every aspect of its design and functionality.



At the heart of our product lies the unique fusion of PTFE and FKM materials, which ensures unparalleled sealing efficiency against a wide spectrum of media – from water and oil to gas, bases, and even aggressive acids. This versatility makes our valve seal ring an indispensable component in industries where purity and performance cannot be compromised. The DN40-DN500 size range caters to a broad scope of applications, ensuring a perfect fit for valve, gas, and fluid control systems in pharmaceutical, food and beverage, and wastewater treatment plants, among others. Every aspect of this seal ring, from its pressure range (PN16, Class 150, PN6-PN10-PN16) to its port size (DN50-DN600), has been meticulously engineered to cater to the high demands of modern industry. Its adaptable color options, customizable hardness, and various connection types (wafer, flange ends) allow for seamless integration into existing systems. The DN40-DN500 Compound Butterfly Valve Seal Ring not only meets current ANSI, BS, DIN, and JIS standards but sets a new benchmark for what the industry should expect from a sanitary compound butterfly valve liner. Whether you're seeking to upgrade your current system or implementing new installations, our product promises to deliver performance, reliability, and purity, ensuring your operations run smoothly and efficiently.
