Ball Valves

When you need to isolate a water supply quickly, reliably, and completely, a ball valve is the preferred choice for both professional plumbers and confident DIYers. At the DIY Hardware Store, our ball valves provide a straightforward shut-off solution for domestic plumbing systems, heating circuits, and cold water pipework.

A ball valve operates via a quarter-turn lever handle that rotates a bored stainless steel or brass ball within the valve body. When the bore aligns with the pipe, flow is fully open. A 90-degree turn closes it completely, with no intermediate settings and no gradual wear from repeated partial turns that affects gate valves over time. This makes ball valves both faster to operate in an emergency and more durable over thousands of cycles.

They're used as service valves on appliances, as isolators on individual circuits, as main stop valves, and throughout heating and hot water systems wherever a dependable, long-lasting shut-off is needed. Compression-ended versions suit standard copper pipe and are compatible with most UK domestic plumbing configurations.

Whether you're installing a new radiator, adding a service valve to an appliance connection, or replacing an old, weeping gate valve with something more reliable, browse our ball valves range at the DIY Hardware Store for the right size and connection type for your project.
