Metal Seated Ball Valve

Key Features:

High Temperature Resistance:

Can withstand temperatures up to 500°C (932°F) or more depending on materials used (e.g., Inconel, Stellite, Tungsten carbide coatings).

Ideal for steam, thermal oil, and hot gas applications.

Superior Wear Resistance:

Hard-faced metal seats (with coatings like Tungsten Carbide, Chromium Carbide, or Stellite) provide excellent resistance to erosion and abrasion.

Suitable for media with solid particles, slurry, or corrosive fluids.

Tight Shutoff:

Despite being metal-to-metal, many designs meet Class V or VI leakage standards using advanced lapping and surface treatment processes.

Fire-Safe Design:

Metal seated valves are inherently fire-safe, maintaining seal integrity in case of fire—often certified to API 607 or ISO 10497.

Blowout-Proof Stem & Anti-Static Devices:

Enhances operational safety in high-pressure, flammable, or hazardous environments.

Long Service Life:

High durability under frequent cycling and harsh conditions reduces maintenance and operational downtime.

Applications:

Oil & Gas:

High-pressure and high-temperature services such as refining, gas processing, and upstream wellhead control.

Petrochemical & Chemical Plants:

For corrosive, abrasive, and toxic media, including acids, alkalis, and slurries.

Power Generation:

In steam systems, turbine bypass, and high-temperature feedwater circuits.

Mining & Minerals:

Handling of slurry, tailing lines, and other abrasive media.

Pulp & Paper:

Used in black liquor, green liquor, and other fibrous or corrosive flows.

Marine & Offshore:

Seawater injection systems, ballast systems, and fire protection lines
