The heart of our Keystone Butterfly Valves lies in the synergy between Polytetrafluoroethylene (PTFE) and Ethylene Propylene Diene Monomer (EPDM) in our valve seals. This combination not only ensures unmatched resilience across a broad temperature range of -20° to +200° Celsius but also guarantees compatibility with a wide array of media, including water, oil, gas, base oil, and even corrosive acids. Whether your application involves simple water transport or handling aggressive chemicals, our valve seals are engineered to deliver unparalleled performance. Designed to be versatile, our Keystone Butterfly Valves offer a seamless fit for various connection types, including wafer, flange ends, and duel configurations, across an extensive size range from DN50 to DN600. Adhering to international standards such as ANSI, BS, DIN, and JIS, these valves are customizable in hardness and color to meet specific operational requirements. The valve type can vary from the wafer type centerline to the lug type double half shaft butterfly valve without pin, highlighting our commitment to providing solutions that are both adaptable and reliable for every conceivable application. With meticulous attention to detail, we ensure that each valve is a testament to durability and efficiency, capable of withstanding the most demanding working conditions, especially in environments prone to acid and alkali exposure.
