4" Stainless Steel Full Port Ball Valve

Ball valves are manufactured in a wide range of sizes, typically from 1/4 inch up to 12 inches or larger for industrial applications. Common sizes include 1/2", 1", 2", 3", and 4", with full port and standard port configurations available depending on flow and pressure requirements.

A 2-way ball valve controls flow between two ports, typically functioning as an on/off shutoff valve. A 3-way ball valve has three ports and can divert, mix, or redirect flow between multiple lines, making it suitable for more complex fluid routing in production and process systems.

A full port ball valve has a bore diameter matching the pipeline size, allowing unrestricted flow and minimal pressure drop. Standard port valves have a smaller bore, restricting flow slightly. Full port designs are preferred for applications requiring pigging or high flow capacity.

Stainless steel ball valves are commonly constructed from 304 or 316 stainless steel for the body and ball, offering excellent corrosion resistance. Seats and seals are typically made from PTFE or reinforced PTFE to withstand chemical exposure and maintain a reliable seal across a range of temperatures.

4-inch stainless steel ball valves are typically available in Class 150, Class 300, and Class 600 pressure ratings, with some high-performance models rated higher. The appropriate rating depends on system pressure, temperature, and the specific application within drilling, production, or industrial processes.

Yes, high-temperature ball valves are designed with specialized seat and seal materials, such as reinforced PTFE or metal seats, to withstand elevated operating temperatures. These valves are engineered for demanding process conditions found in oil and gas production and industrial manufacturing environments.
