The metal hard-sealed high-temperature ball valve is a specialized valve device utilizing a ball as the valve core. Operating on the principle of rotary motion, it ensures fluids are cut off or circulated through precise contact between the sphere and the metal sealing surface. This design facilitates rapid opening and closing while maintaining exceptional sealing integrity under extreme thermal conditions.
Excellent High-Temperature Resistance: Constructed using special alloy materials such as Cr-Mo-Ti alloy, these valves are engineered to withstand extreme working environments. This material selection ensures high strength and hardness are maintained even when handling high-temperature media.
Superior Sealing Performance: Utilizing metal-to-metal contact, these valves form a rigid seal that offers outstanding resistance to wear and corrosion, ensuring a prolonged service life in harsh industrial settings.
The high-temperature sanitary ball valve plate and seat utilize oblique conical structures with temperature and corrosion-resistant alloys welded on the surfaces. These alloys are specifically chosen to withstand routine wear caused by corrosive chemicals and abrasive mediums.
A specialized spring fixed between regulating ring pressure plates effectively compensates for tolerance zones and elastic deformation of the valve stem under high system pressure, solving sealing challenges in two-way interchangeable medium transportation.
