The Fire-Safe High-Performance Butterfly Valve is designed with dual seats to ensure optimal sealing and reliability. The primary seat is constructed from RPTFE (Reinforced Poly Tetrafluoroethylene), providing excellent sealing performance for tight shut-off and preventing leakage. This soft seat material enhances the valve's overall functionality by offering superior sealing properties. In addition, the valve features a fire-safe metal seat, providing enhanced resistance to high temperatures and ensuring reliable operation during fire incidents. The combination of the RPTFE soft seat and the fire-safe metal seat ensures consistent performance in both normal and emergency conditions, making this valve an ideal solution for applications where safety, efficiency, and reliability are critical.
