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.
