RIIFO F18 MLCP Press Valves

RIIFO F18 valves bring quarter-turn isolation directly into a multilayer composite pipe (MLCP) installation. Manufactured in brass and WRAS-approved for use on wholesome water supplies, each valve connects to PEX/AL/PEX multilayer pipe using the same press-fit connection as the rest of the F18 system, so shut-off points can be built into the pipework as it is installed rather than added around it with extra couplers and adaptors.

The range is multi-profile, compatible with both TH and U-profile press jaws, so installers with either jaw set can press the valves alongside the rest of the system with the tools they already own. All valves in the range share a maximum working pressure of 10 bar and a maximum working temperature of 95°C, making them suitable for both hot and cold water services, and every valve is available with a red or blue handle for clear identification of hot and cold lines.

Each valve in the F18 range uses a low-profile butterfly handle in place of a protruding lever. The handle sits much flatter against the pipe, an advantage where valves are installed in confined spaces, behind bath panels, inside boxed-in pipe runs or under kitchen units, where a standard lever can foul against surrounding surfaces or be awkward to reach.

Despite the compact profile, operation remains a full quarter-turn: a simple 90-degree twist takes the valve from fully open to fully closed, giving quick isolation when a fixture or section of pipework needs to be shut off. The red and blue handle options make hot and cold lines instantly distinguishable where supplies run side by side, reducing the chance of the wrong line being isolated during maintenance.

• With press connections on both sides, this valve fits directly into a multilayer pipe run for mid-run isolation. There is no need for separate couplers on either side, keeping the joint count down and the installation neat.

• Pairing a press connection with a male BSP thread, this valve screws directly into female-threaded appliances, tank connections and fittings while connecting straight into the multilayer pipe on the other side. It builds shut-off into the transition point itself, so the appliance can be isolated at the exact place it connects.

• The reverse configuration, combining a press connection with a female BSP thread that screws onto male-threaded tap tails, appliance connectors and fittings. This makes it the natural choice for isolating taps and terminal fittings at the point of connection.

F18 valves are suited to hot and cold water isolation duties throughout domestic and commercial multilayer installations. Typical uses include isolating individual fixtures such as taps, toilets, showers and appliances so they can be serviced without draining the wider system, sectioning off zones or floors of a larger installation for phased commissioning or maintenance, and providing clear shut-off points at cylinders, tanks and manifolds.

Building isolation into the pipework at first fix is far quicker and cheaper than adding it later, and the press valves make it easy to place shut-off points exactly where future access will be most useful.

• F18 valves provide quarter-turn shut-off within RIIFO multilayer pipe installations. They are used to isolate fixtures, appliances and sections of pipework for maintenance and repair without draining the whole system, on both hot and cold water services.

• A butterfly handle is a compact, low-profile alternative to a standard lever. It sits much flatter against the pipe, making it well suited to valves installed in tight spaces, while still operating with the same simple quarter-turn from open to closed.

• Yes, F18 valves are WRAS approved, confirming their suitability for use on wholesome water supplies in the UK.

• All valves in the range are rated to a maximum working pressure of 10 bar and a maximum working temperature of 95°C, covering hot and cold water services in domestic and commercial installations.

• Yes. The press ends are multi-profile and compatible with both TH and U profile jaws, so they can be pressed with the same tools used for the rest of the F18 fittings range.

• Yes. The standard butterfly ball valve has press connections on both sides, so it installs directly into the pipe run with no additional couplers, giving mid-run isolation exactly where it is needed.

For isolating a section of pipework mid-run, choose the standard butterfly ball valve with press connections on both sides. For connecting to a female-threaded appliance, tank or cylinder with shut-off built into the joint, choose the male ball valve. For connecting to a tap tail, appliance connector or any male-threaded fitting, choose the female ball valve.
