A guide to specifying valves for large commercial buildings
W
hen planning the plumbing system for a large commercial building, there is a lot that specifi ers will need to consider
including the demands for each building, complying to all necessary regulations, and any maintenance requirements. Then there is also the challenge many specifi ers
are facing, which is making our buildings more energy effi cient and economical in the long term. All these factors will play an important role when specifying the right plumbing fi xtures and fi ttings that will be needed, including the valves.

Valves are an important, but often overlooked, part of this puzzle. Eric Winter, RWC’s EMEA director of product development (valves), shares his advice on everything that a specifi er needs to know when working on plans for large commercial buildings
pressure reducing valves (PRVs) and thermostatic mixing valves (TMVs), but there are also valves that are designed specifi cally for large multi-occupancy buildings, like the Tenant Valve. Here are the most common valves you should consider in your next specifi cation:
Pressure reducing valves (PRVs): From PRVs to TMVs, six valves to consider in your specifi cation When working on a commercial property, there
are many valves that you will come across that are also used in a domestic setting. These include
These valves work by reducing a high inlet pressure to a safer, lower pressure at the outlet. Water pressure in the UK can vary from 1 bar to 20 bar, so PRVs are important to ensure the risk to plumbing systems is minimised. In large commercial buildings, high pressure is often needed to allow for water to
