Wafer Pattern WRAS Motorised Butterfly Valves

Any water fitting, which whilst operational, will carry or acquire water from the public mains water supply in the united kingdom, need to comply with the Water supply regulations or Scottish Byelaws. This requires that a water fitting must not cause waste, misuse, undue consumption or contamination of the water supply and must be ‘of an appropriate quality and standard’.

Butterfly valves are used in vast numbers because with correctly matched materials of construction to their intended application, they offer a reliable and effective means of controlling flow in pipes. With several different designs that achieve the same objective, butterfly valves vary enormously in price from very low-cost throw-away types for simple, basic water isolation applications to very expensive, specialist butterfly valves for the most demanding and critical applications.
