FAQ
Q: What is a Metal Hard Seal Ball Valve?
A: A metal hard seal ball valve is a type of ball valve with metal-to-metal sealing surfaces instead of soft materials like PTFE. This design ensures tight shutoff under high pressure, high temperature, and harsh media conditions.
Q: What are the advantages of a metal hard seal compared to soft-sealed valves?
A: Metal hard seals provide superior durability, long service life, and resistance to wear, high temperature, and corrosive media. They are ideal for applications where soft seals would degrade quickly.
Q: What specifications should buyers check before purchasing?
A: Key specifications include pressure class (PN16–PN160 / Class 150–900), size range, body material (stainless steel, carbon steel, alloy steel), end connection type (flanged, threaded, welded), temperature range, and ball/seat material grade.
Q: Where are Metal Hard Seal Ball Valves commonly used?
A: They are widely used in oil & gas, petrochemical, power plants, chemical processing, and other industries requiring high-pressure, high-temperature, or abrasive media control.
Q: What factors affect the price of a Metal Hard Seal Ball Valve?
A: Pricing depends on valve size, pressure class, material grade, seat and ball design, certifications (API, ISO, CE), and additional options like anti-static devices, fire-safe design, or gear-operated handles.
