The colour of the handles on Bromic ball valves are used to distinguish their usage between gas and water.
Valves with a yellow handle are gas valves and are AGA-approved for use with Natural Gas and LPG.
Valves with a green handle are water valves and are WaterMark-approved for use with potable water. Almost all of Bromic's green handle valves are also AGA-approved for use with gas, with exceptions such as 1210437.
Refer to product information to review if a valve is compatible with gas and/or water pipelines.
Both ball valves and butterfly valves are valves that are used to control the flow of water or gas in a pipe system. Internally, butterfly valves consist of a thin disk and ball valves consist of a sphere-like disc that rotates as the handle is turned.
Whilst butterfly valves are usually recommended for use with larger pipe diameters, ball valves provide a tighter seal and are hence suitable for high-temperature and pressure services. Bromic supplies a wide range of ball valves with different thread connections and lever types for gas and water applications.
Please note: Butterfly valves should not be confused with butterfly handles (also known as T handles).
To choose the right air admittance valve, you'll need to know the fixture unit of the pipe and the airflow capacity required. Read more

Push-fit pipes are quick and easy to install and can be easily separated. Solvent-weld pipes use solvent cement to make a strong joint, making them suitable for permanent fixtures.
Push-fit connections connect with push-fit pipes and solvent-cement connections connect with solvent-weld pipes. Some valves come with a removable adaptor that allows it to fit either connection, for example on the Bromic Air Admittance Valve 110mm.
No, the Air Admittance Valve (110mm) and the Air Admittance Valve (with Adaptor for 32-40-50mm) are intended for in cupboard use, not on roofs.
Air admittance valves allow air to freely enter the pipeline and prevents foul gas from escaping into the building. Manufactured from high-quality polyvinyl chloride, these valves save the need to penetrate the outlet roof shell, and reduce the cost of pine, expensive fittings and roof flashings. Watermark approved WM-040105.
