Overview
What Is a Metal Seated Ball Valve?
A metal seated ball valve is a quarter-turn shut-off valve designed with metal-to-metal sealing surfaces between the ball and seat. It is commonly used in severe service applications where high temperature, abrasive particles, erosion, or demanding media make soft seated valves less suitable.
Compared with soft seated ball valves, metal seated designs offer better wear resistance, higher temperature tolerance, and improved durability in harsh operating conditions.

FAQ
Frequently Asked Questions
Common questions about metal seated ball valve design, severe service capability, hard-facing options, and application.
What is the difference between a metal seated ball valve and a soft seated ball valve?
A metal seated ball valve uses metal-to-metal sealing surfaces, while a soft seated valve uses polymer sealing materials such as PTFE. Metal seated designs are generally preferred for high temperature, abrasive media, and severe service conditions.
Why is a metal seated ball valve suitable for high temperature service?
Because metal sealing surfaces are more stable at elevated temperatures where soft sealing materials may deform, degrade, or lose sealing reliability.
Are metal seated ball valves suitable for particle or slurry media?
Yes. They are commonly used in applications involving solids, ash, powder, slurry, or abrasive particles where stronger wear resistance is required.
What is hard facing in a metal seated ball valve?
Hard facing is a surface treatment or overlay process applied to the ball and seat sealing surfaces to improve hardness, wear resistance, erosion resistance, and sealing life.
Can metal seated ball valves be automated?
Yes. They can be supplied with gear, pneumatic, or electric operation depending on torque requirement, operating frequency, and project specification.
How do I choose the right metal seated ball valve?
Selection should be based on temperature, solids content, media properties, pressure class, valve size, cycle frequency, end connection, and the required surface treatment or hard-facing specification.
