22mm full bore isolating valves provide efficient shut-off while maintaining unrestricted flow through the system. Unlike standard isolators, the full bore design ensures the internal diameter matches the pipework, allowing water to pass through freely with minimal turbulence or pressure drop. This makes them especially valuable in high-flow domestic systems and heating circuits where performance is key.Ideal for both hot and cold water applications, these valves are simple to install and operate. Their compact design makes them perfect for use under sinks, on heating loops, or near appliances where easy access and reliable control are essential.

Key features and benefits of these valves.

Key Features

Internal diameter matches 22mm pipework, ensuring unrestricted water flow. This minimises pressure loss and supports system efficiency.

Key Features

Allows quick and effective shut-off of individual circuits or appliances. Ideal for maintenance or emergency repairs without disrupting the whole system.

Key Features

Slimline body fits neatly into tight spaces like kitchen units or plant rooms. Simple to install using compression fittings or push-fit options.

In any plumbing or heating system, isolation valves are essential — but when flow performance matters, a full bore valve is the superior choice. Standard isolators can restrict flow and reduce efficiency, especially in high-demand setups. Full bore isolating valves solve that issue by allowing water to pass through without obstruction, keeping system pressure steady and appliances working efficiently.

They also provide a convenient, localized shut-off point, reducing the need to isolate or drain the entire system for simple maintenance or repairs. Whether you're working on a heating loop, bathroom upgrade, or appliance installation, a 22mm full bore isolating valve gives you full control with zero compromise on performance.

These valves are commonly found in domestic water and heating systems where high flow is important — such as on hot water feeds to showers, boilers, cylinders, and radiators. They're also used to isolate individual loops in underfloor heating, or to shut off sections of cold mains or kitchen/bathroom supplies without losing flow rate.

You’ll often see them installed near washing machines, sinks, unvented cylinders, and combi boiler feeds. Their 22mm sizing makes them ideal for larger residential properties and small commercial setups with standard pipework.

It’s used to isolate sections of a plumbing or heating system, allowing for maintenance or repairs without shutting off the entire system — while ensuring minimal flow restriction.

Full bore means the internal diameter of the valve matches the pipe size (22mm in this case), allowing maximum flow with minimal pressure loss.

They’re typically installed on hot and cold water supplies, heating circuits, and near appliances such as water cylinders, boilers, and pumps.

Yes — full bore isolating valves can be used on both hot and cold water lines, as long as they’re rated for the system’s temperature.

Most feature a lever or screwdriver slot for manual on/off control, offering quick and easy shut-off.

Yes — they’re often used to isolate heating loops, radiators, and components like pumps or valves for servicing.

It won’t increase pressure, but it helps maintain system performance by avoiding the restriction often seen in reduced-bore valves.

Many are, especially those used in potable water systems. Check individual product listings for certification.

Typically brass or nickel-plated brass for corrosion resistance and durability in domestic and commercial systems.

They’re low maintenance, but turning the valve periodically helps prevent seizing, especially in rarely used systems.

Yes — they often feature compression ends, making them simple to fit onto 22mm copper or plastic pipework with basic plumbing tools.

Yes, but they should be protected from freezing temperatures and direct weather exposure to avoid damage or seizing.
