Keystone Valve Seat: Premium PTFE & FKM for Superior Sealing

In the world of industrial valves, the integrity and reliability of your system's components are paramount. Sansheng Fluorine Plastics introduces its top-of-the-line Bray butterfly valve liner, engineered to redefine standards in fluid control. At the heart of our innovation lies the keystone valve seat, a product designed not just to meet but to exceed the expectations in applications ranging from water and oil to gases, bases, and even acid environments. Crafted from an advanced combination of PTFE and FKM (FPM), our valve seats are the epitome of resilience and flexibility. PTFE, renowned for its exceptional chemical resistance and low friction properties, ensures that our valve seats can handle a wide array of media with unparalleled efficiency. Complemented by FKM, a material celebrated for its high-temperature tolerance and resistance to chemicals, the keystone valve seat emerges as a superior choice for any setting requiring tight sealing and long-term reliability. Our Bray butterfly valve liners come in a variety of sizes, spanning from DN50 to DN600, making them a versatile solution for numerous applications. Whether you are dealing with valves for water, oil, gas, or even more aggressive media like base oils and acids, these liners stand ready to deliver. Notably, our offering includes the Wafer Type Centerline Soft Sealing Butterfly Valve and the pneumatic Wafer Butterfly Valve, both available in colors that can be customized to your request. The compatibility with wafer and flange ends, along with a customizable hardness level, ensures that our valves can be tailored to the specific needs of your system. Moreover, the choice of seat materials - ranging from EPDM to NBR, EPR, PTFE, and even more specialized options like FKM and FPM - guarantees that every application finds its perfect match in our products.



The design focus extends beyond mere materials and sizes, venturing into the structural integrity and ease of integration of the valves. Opting for a lug type double half shaft butterfly valve without pin, our products offer a secure, robust, and efficient solution that simplifies installation while maximizing performance. This, combined with our commitment to innovation and quality, ensures that the keystone valve seat at the heart of our butterfly valve liners stands as a beacon of excellence in the industry. Sansheng Fluorine Plastics prides itself on delivering products that not only meet but also exceed industry standards. With a focus on superior materials, meticulous design, and a wide range of options, our Bray butterfly valve liners, powered by the keystone valve seat, are set to revolutionize fluid control across diverse sectors.
