Features
  • High-Temperature and High-Pressure Performance: Metal seated high performance butterfly valves use metal sealing materials such as stainless steel and alloys, providing excellent performance in high-temperature and high-pressure applications.
  • Corrosion Resistance: Metal sealing materials typically have strong corrosion resistance, reducing the risk of leaks and corrosion.
  • Long Service Life: Due to the durability and wear resistance of metal sealing materials, metal seated butterfly valves typically have a longer service life, reducing maintenance and replacement frequency.
