22 MODERN BUILDING SERVICES FEBRUARY 2021 FEATURE PIPED SERVICES PIPED SERVICES I n recent years, valve technology has advanced in response to challenges faced by engineers and installers. Valves have a low profile in the world of building services specification. However, their impact on the efficient and effective operation of hydronic systems should not be underestimated. Without correctly specified, installed and commissioned valves, today’s heating, cooling and water systems could not operate. Hydronic systems This is a system in which water is the medium that carries heat around a building, must be kept in constant balance. A poorly- performing hydronic system can mean that heat is not delivered to some areas of a building. For example; causing discomfort for occupants and issues for the facilities management team. What’s more, an imbalanced hydronic systemwill also use more energy than it should, leading to higher building operating costs. Valve technology An area that has been advancing over the past few years. It has developed to help engineers and installers meet challenges such as the growing number of high rise developments, minimal spaces for plant rooms and the need to complete projects to ever-tighter deadlines. For specifiers, the humble valve is a product that can help to make design and delivery of efficient systems for buildings much more straightforward. Recent valve evolution includes the pressure independent control valve (PICV), or the fixed orifice double regulating valve (FODRV). However, one of the most significant advances in valve fitting technology has been the introduction of the press-installation method. Press-fit valves offer a faster, safer and more reliable solution for installers. Darren Baxter , Albion Valves explains why valves are an often-overlooked part of a building services system.
