Guide to 22mm Ball Valves: Reliable Plumbing and Heating Control
When it comes to plumbing and heating systems in residential and commercial settings, 22mm ball valves are one of the most reliable and widely used components on the market. These compact, quarter-turn valves offer fast shut-off, simple installation, and long-lasting durability — making them a staple in UK plumbing configurations.
What Are 22mm Ball Valves?
22mm ball valves are isolation valves designed to control the flow of water through 22mm pipework. With a full bore design, the internal hole of the valve is the same diameter as the pipe, ensuring unrestricted water flow and minimal pressure loss. Unlike older gate valves or stopcocks, 22mm ball valves operate with a simple quarter-turn handle that instantly opens or closes the flow, offering a far more modern and efficient alternative.
These valves are typically made from high-quality brass or stainless steel and come with compression ends for quick and easy installation — no soldering required. Whether you’re upgrading a heating system, fitting a combi boiler, or simply adding isolation points for maintenance, 22mm ball valves provide unmatched convenience and performance.
Why Are 22mm Ball Valves So Important?
Flow control is vital in plumbing systems, especially those involving heating or high-pressure supply lines. 22mm ball valves allow engineers and homeowners to isolate specific sections of a system for repairs, upgrades, or emergency shutdowns without draining the entire setup. Their full bore design means that even during regular use, flow rates are maintained, pressure remains stable, and water hammer risk is reduced.
Moreover, the build quality of 22mm ball valves ensures long-term reliability. With WRAS-approved options available, these valves meet strict UK standards for use with potable water, giving both installers and end users peace of mind.
Common Applications for 22mm Ball Valves
You’ll commonly find 22mm ball valves in:
Domestic central heating systems
Combi boiler installations
Cold and hot water supply lines
Underfloor heating zones
Light commercial buildings
Maintenance and isolation points
Their ease of use and compatibility with standard UK pipe sizes make them ideal for a wide range of applications, from residential bathrooms to plant rooms in commercial facilities.
Key Benefits of 22mm Ball Valves
Full Bore Design: Allows maximum water flow with minimal pressure drop.
Quarter-Turn Operation: Quick and easy shut-off in emergencies or during maintenance.
Durable Materials: Typically manufactured from corrosion-resistant brass or stainless steel.
Simple Installation: Compression ends make it easy to connect to copper or plastic pipes.
WRAS Approved Options: Suitable for use with potable water systems.
Low Maintenance: Long service life and minimal upkeep required.
When selecting a 22mm ball valve, it’s important to consider the material, handle type, and certification. For tight spaces, a butterfly handle might be preferable over a lever. For high-use systems, opting for a valve with a reinforced handle and PTFE seals can further improve reliability.
Always check for WRAS approval when installing valves in drinking water systems. This ensures compliance with UK regulations and guarantees that the valve won’t leach harmful substances into the water supply.
Final Thoughts
Whether you're a professional plumber or a DIY enthusiast, 22mm ball valves are an essential component for controlling and isolating flow in plumbing and heating systems. Their simple design, long-lasting performance, and compatibility with UK-standard 22mm pipework make them a top choice for any installation. If you're looking for a cost-effective, efficient, and durable valve solution, 22mm ball valves deliver on all fronts.
