Union Ball Valves are available in two primary types: Single Union and Double Union Ball Valves, each offering unique features to suit various applications. Single Union Ball Valves have a union connection on one end, facilitating easy removal and maintenance while keeping the other end fixed within the piping system. Sub-variants of single union valves include threaded models for simple screw connections and socket models designed for secure socket welding. In contrast, Double Union Ball Valves feature union connections on both ends, allowing for complete valve removal without disrupting the attached piping.

These can also be found in threaded and socket variants, as well as flanged options for robust connections in larger systems. Additionally, union ball valves are manufactured from various materials, including brass for general applications, stainless steel for high-pressure environments, and plastic (such as PVC or CPVC) for chemical resistance. Available in multiple sizes and pressure ratings, Union Ball Valves are versatile components suitable for a wide range of fluid control needs in residential, commercial, and industrial settings.
