Metal Hard-Sealed High-Temperature Ball Valve

High Temperature Ball Valve

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.

Valve Header
  • Patented Single-Seat Design: Features a flat spring set acting through a hard-faced bearing against the bottom ball shaft, providing sufficient initial load for tightness even at low delta P.
  • Solids-Proof Technology: Proven in qualification tests to be effective for slurry service containing solid particles.
  • Customizable Tightness Rates: Standard leakage rates follow ASME/ FCI 70-2 Class VI/V, with tighter shutoff available upon request.
  • Standard Extension Bonnet: Designed based on specific temperature ranges to protect the stem and packing.
  • Versatile Sealing: Supports both uni-directional and bi-directional sealing configurations.
Technical Specs

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.

Frequently Asked Questions

What defines a "hard-sealed" high-temperature ball valve?
It refers to the metal-to-metal contact between the ball and the valve seat, utilizing hard alloys like Cr-Mo-Ti or Stellite to ensure sealing integrity at temperatures where soft seals would fail.
In which industries are these valves commonly used?
They are widely applied in petrochemical, metallurgy, electric power, and natural gas industries for controlling high-temperature water, steam, molten metal, and corrosive chemicals.
Can this valve handle media with solid particles?
Yes, the patented single-seat design and hard-faced bearings make these valves solids-proof, suitable for tough applications like slurry service.
What are the available body materials for these ball valves?
Standard materials include 304, 304L, and 316L stainless steel, as well as Carbon Steel (WCB) and Low Carbon Steel (LCB) depending on the specific application requirements.
Does the valve support bi-directional flow?
Yes, the design allows for both uni-directional and bi-directional sealing, with special spring compensation structures to ensure tight shutoff in both directions.
What is the standard lead time for customized valves?
The typical delivery time is between 15 to 25 days, depending on the specifications and customization requirements.
