Welded Ball Valve Banner.jpg
2025/11/27

Welded ball valves are a crucial component for industries requiring high reliability, sealing performance, and durability. Unlike threaded or flanged ball valves, welded ball valves provide stronger, leak-free connections, ideal for medium-pressure and high-temperature applications. There are two primary types of welded ball valves: butt-welded and socket-welded, each offering unique benefits for specific applications. These valves excel in industries such as oil & gas, chemical processing, power generation, and water treatment, where leak prevention and reliability are paramount. SLVCN’s welded ball valves are trusted worldwide for their strength, corrosion resistance, and long-term performance in demanding environments.
