Jaquar Angular Stop Cock is the small isolating valve that sits between a wall supply and a fitting — a basin tap, a health faucet, a cistern or a geyser inlet — turning the water through 90 degrees and letting you shut off that one fitting on its own. Available here in two ranges: Astra and Kubix Prime.

The value of an angle valve is out of all proportion to its price, and it is a maintenance decision more than a plumbing one. Without one, servicing a dripping tap means shutting off water to the entire bathroom or the whole flat. With one, you close a single valve and get on with the job. A bathroom fitted without angle valves is irritating to live with for the next twenty years.

What separates these from a generic angle cock is that both are quarter turn. A traditional valve seals by compressing a rubber washer against a seat, and rubber perishes — which is exactly why old angle cocks start weeping, and why tightening them harder only buys a few months. A quarter turn valve seals with two ceramic discs that rotate 90 degrees against each other. Ceramic does not perish, there is no washer to replace, and the handle moves from fully open to fully shut in a single quarter turn. Jaquar rates the mechanism at 200,000 cycles to EN 200.

The pressure figures are worth reading if you live above the lower floors. Recommended working pressure is 0.5 to 5 bar, but the valve passes water tightness at 16 bar and resists 25 bar — five times its rated maximum. In an upper-floor high-rise, where static head pushes supply pressure well beyond what a domestic valve normally sees, that margin is the difference between a valve that holds and a burst fitting behind a vanity.

Both variants are solid brass, chrome plated, take a standard 15 mm (½" BSP) connection, and are supplied with a matching wall flange — the chrome plate that covers the rough opening where the pipe leaves the wall. Without it, the installation looks unfinished.

Which Range Should I Choose?

Mechanically they do the same job to the same standard. Choose on styling — an angle valve sits in plain view beneath a basin, so it is worth matching it to the taps rather than leaving one fitting that does not belong. If your bathroom is being fitted in Kubix Prime, take the Kubix Prime valve.

Technical Specifications

Recommended Applications

1) Why does this cost more than an ordinary angle cock?

Because of how it seals. A traditional valve compresses a rubber washer against a seat, and rubber perishes — which is why old angle cocks start weeping and why tightening them harder only buys a few months. This is a quarter turn valve sealing on two ceramic discs. Ceramic does not perish, there is no washer to replace, and Jaquar rates the mechanism at 200,000 cycles to EN 200. You are paying for the failure mode not happening.

2) What does an angle valve actually do, and do I need one?

It is an isolating valve for a single fitting. Close it and you can service a tap, health faucet or cistern without turning off water to the rest of the bathroom or the flat. It is worth fitting one at every supply point — a bathroom without them means a full shut-off every time anything needs attention.

3) How many should I order?

Count your supply points, not your bathrooms. A typical bathroom needs one for the basin tap, one for the health faucet, one for the cistern, and often one for the geyser inlet — so three or four. Order them together rather than discovering the shortfall mid-installation.

4) Is the wall flange included?

Yes — both variants ship with a matching chrome wall flange. That is the plate that covers the rough opening where the pipe comes out of the wall. Without one the installation looks unfinished, and some brands charge for it separately.

5) Astra or Kubix Prime — which should I choose?

Styling, not performance. Both are quarter turn ceramic disc valves in solid brass with a wall flange, built to the same standard. The Astra has a triangular handle and suits general use; the Kubix Prime carries that range's squared geometry and matches Kubix Prime taps. An angle valve sits in plain view under a basin, so if your bathroom is being fitted in Kubix Prime, take the matching valve.
