High Temperature Ball Valve

A high temperature ball valve is a robust quarter-turn valve engineered to maintain structural integrity and smooth operation in thermal environments from 200°C up to 650°C. To withstand aggressive thermal cycles without material breakdown, the valve is forged or cast from heat-resistant alloys, such as stabilized 321 or 347 stainless steel, or Hastelloy C-276, providing superior creep resistance and oxidation immunity. The internal seating replaces standard polymers with precision-machined metal-to-metal seats, often hard-faced with Stellite overlays, to eliminate the risk of melting or cracking. The valve features a modular three-piece body architecture configured with specialized thermal expansion clearances. Thermal utility contractors and petrochemical process engineers can eliminate thermal binding and secure long-term high-heat safety by importing certified high temperature ball valves directly from leading manufacturers in China via our advanced B2B commercial platform.
