The fire-safe high-performance butterfly valve is designed with two distinct seats to ensure optimal functionality. The primary seat is made of RPTFE (Reinforced Poly Tetra Fluoro Ethylene), which provides a tight shut-off and effectively prevents leakage. This soft seat material offers excellent sealing properties, enhancing the overall performance of the valve. Additionally, the valve is equipped with a fire-safe metal seat, providing superior resistance to high temperatures and ensuring reliability under fire conditions. The combination of the RPTFE soft seat and the fire-safe metal seat guarantees consistent performance in both normal and emergency situations, making this valve an ideal choice for applications where safety and efficiency are critical.
