Metal Seated Ball Valve SS316 | High Temperature and Fluids with Solids
The metal seated ball valve (hard seal) in SS316 stainless steel is designed to operate reliably in high-temperature applications and abrasive conditions where soft seats are not suitable. Therefore, it is the ideal choice for severe services with particles, slurries, and hot corrosive fluids.
Its robust design incorporates hardened SS316+Ni55 metal seats, ensuring wear resistance and a long service life even under severe operating cycles. Additionally, it offers bidirectional sealing, low operating friction, and dimensional stability under extreme thermal variations.
It is ideal for demanding industrial processes such as superheated steam, corrosive fluids, hot hydrocarbons, abrasive gases, and high-temperature slurries.

Applications of the Metal Seated Ball Valve
The metal seated ball valve operates reliably in high-temperature, high-pressure, and abrasive conditions. Below are the most common use cases:
Energy and Steam: Handles saturated and superheated steam in power generation and distribution systems. It is also common in condensate lines and high-pressure boiler systems.
Petrochemical and Refineries: Controls hot hydrocarbon lines in refineries and petrochemical plants. Furthermore, its metal seat resists erosion in fluids with solid particles where soft seats prematurely fail.
Corrosive and Abrasive Gases: Regulates and isolates corrosive or abrasive gases, including combustion gases. Therefore, it is a reliable option in industrial gas treatment systems.
Thermal Services: Operates in heat exchanger systems, industrial furnaces, and demanding thermal services. Similarly, it conveys thermal oils and high-temperature heat transfer fluids.
Mining and Metallurgy: Handles hot slurries, suspensions, and liquid slags with abrasive particles. Therefore, it reduces maintenance in mechanically demanding environments.
Chemical Processes: Works with aggressive solvents and corrosive media at elevated temperatures. Consequently, it offers greater durability than valves with elastomeric seats in these services.
