22mm ball valves play a critical role in plumbing and heating systems by offering fast, reliable flow isolation. Their full bore design ensures that water or fluid can pass through without restriction, helping maintain consistent pressure and efficient system performance. This is especially important in domestic heating or hot water setups, where reduced flow can impact appliance function or energy efficiency.

Their importance also lies in their ability to quickly shut off flow during maintenance or emergencies. Unlike traditional gate valves, the quarter-turn handle on a ball valve allows instant operation — making it ideal for both professionals and homeowners who need a dependable and easy-to-use solution. With strong, corrosion-resistant bodies and reliable sealing, 22mm ball valves are a fundamental component in ensuring the safety, efficiency, and reliability of fluid systems.

22mm ball valves are commonly found in domestic plumbing systems, particularly in central heating circuits, hot and cold water supply lines, and combi boiler installations. They're used to isolate sections of pipework, making it easy to carry out maintenance or emergency repairs without draining the entire system.

You'll also find them in commercial buildings, such as offices, hotels, and schools, where 22mm pipework is used for water distribution or heating zones. In some light industrial settings, they’re used for controlling non-aggressive fluids in smaller process lines. Thanks to their simple installation and reliability, they’re a go-to valve for plumbers, heating engineers, and maintenance teams alike.
