Read on to understand…

The sizing of air valves is critical for an application to ensure appropriate surge control and consistent optimum system performance. Often people ask, for example, for an 80mm or 100mm air valve without defining the characteristics of a system. As a result they can receive a variety of options from numerous manufacturers all looking to win the bid. In reality the valve they receive may well have an 80mm or 100mm flanged connection but in an attempt to reduce the competitive cost of the valve often has an orifice that is insufficient for the application. The result is a reduction of flow rates, destructive water hammer, increased maintenance costs and increased running costs.

At MGA Controls we stock a range of air valves that can be combined to offer a variety of functions to rationalise and optimise the system components over a wide range of flow characteristics. These valve combinations can be sized specifically for the application and fitted to existing pipework connections using an appropriate range of flange adapters. Our technical experts are on hand to carry out this service, please call us on +44 (0) 870 803 2001 or email us at
