Jaquar Angular Stop Cock (REGULATING VALVE)

Description

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.
