Product Detail

The Metal-to-Metal Floating Ball Valve with Extended Stem is a heavy-duty, high-performance isolation solution engineered for severe industrial services involving abrasive slurries, high temperatures, or extreme thermal insulation requirements. Featuring a precision-lapped metal seat-to-ball interface hardened with Stellite, Tungsten Carbide, or Nickel-based alloys, this valve guarantees superior resistance to wear, erosion, and high-temperature degradation. The integrated extended stem (bonnet extension) design provides essential clearance for thick pipeline insulation lagging, prevents thermal shock to the stem packing in high-temperature media, and isolates cryogenic temperatures from external actuators in low-temperature applications.

Design Description

Hardfaced Metal-to-Metal Sealing: Ball and seat surfaces are coated or thermally sprayed with wear-resistant alloys (Stellite, WC-Co), providing long-lasting durability in abrasive and solid-laden fluids.
Thermal Isolation Extended Stem: The elevated stem design prevents heat transfer to manual operators or actuators in high-temp loops, and keeps frost/ice formation away from stem seals in cryogenic services.
Floating Ball Flexibility: The floating ball design utilizes line pressure to press the ball against the downstream metal seat, ensuring a reliable initial seal while accommodating normal operational pressure shifts.
Fire-Safe & Anti-Static Design: Naturally fire-safe due to all-metal construction, combined with anti-static grounding to eliminate electrostatic hazard risks in chemical plants.

Application & Function

Metal to Metal Floating Ball Valve With Extend Stem are widely utilized in demanding environments due to their superior material properties:

High-Temperature Chemical Processes: Catalytic cracking and high-temp flue gas or solid-laden fluid lines.
Cryogenic & LNG Services: Liquefied natural gas pipelines requiring extended bonnets to prevent cold-box icing.
Abrasive Slurry Handling: Mining, cement, and paper pulp slurry pipelines where soft seats would rapidly degrade.
