In the realm of industrial flow control, the integration of quality materials and innovative design is paramount. The Keystone Butterfly Valve 990 embodies this principle, offering a superior solution for efficient and reliable fluid management. Crafted by Sansheng Fluorine Plastics, this valve leverages the unmatched synergy of EPDM and PTFE, setting a new standard for performance in a wide range of applications. At the heart of the Keystone Butterfly Valve 990 is its unique seat material - a compound of PTFE (Polytetrafluoroethylene) and EPDM (Ethylene Propylene Diene Monomer). This combination not only ensures exceptional chemical resistance but also provides a broad temperature range of -40°C to 135°C, making it suitable for a variety of media, from water to more aggressive substances. The fusion of PTFE and EPDM enhances the valve's durability and longevity, enabling it to withstand harsh conditions without compromising its functionality or integrity.



Designed for versatility, the valve accommodates a wide range of port sizes from DN50 to DN600, ensuring a perfect fit for any system. Its application in butterfly valves, particularly the Wafer Type Centerline Soft Sealing Butterfly Valve and pneumatic Wafer Butterfly Valve, highlights its adaptability and efficiency in controlling flow. The valve boasts a sleek black color, and its connectivity options include both wafer and flange ends, providing flexibility in installation and maintenance. With seat options such as EPDM, NBR, EPR, PTFE, and more, the Keystone Butterfly Valve 990 is customizable to meet the specific needs of any application, whether it requires lug type double half shaft butterfly valves without pin or other configurations. Sansheng Fluorine Plastics has meticulously engineered the Keystone Butterfly Valve 990 to cater to the demanding requirements of modern industries. By combining the robustness of EPDM with the resilience of PTFE, this valve offers unparalleled performance, ensuring smooth operation and control in systems where reliability and precision are critical. Whether it's for water treatment plants, chemical processing facilities, or HVAC systems, the Keystone Butterfly Valve 990 stands as a testament to quality and innovation in fluid management solutions.
