No specific standard that I have ever come across, chambers tend to be build to ensure the assets are centralised and operable. One thing to always consider when working on the valves in a large chamber is thrusting and the stability of pipework as this can be compromised depending on the installation methods, pipe design, materials and work being completed

Let me add for a DN100 size valve

300mm make-up piece between the valves

can you please share the standard from which you have derived this or is it best engineering practice?

As regards the size of the chamber, if it is merely a distribution point en-route, the size ranges from 2 minuits' to 5 minuites retention period i.e. capacity to accomodate the discharge received in 2 minutes to 5 minutes. For valves there should be no specific criteria in my opinion.

Il y a deux éléments qui agiront sur les dimensions de votre chambre et les espacements entre les vannes : i) les gabarits (size) des vannes et les espaces nécessaires à leurs manutention, et ii) le poids éventuels des vannes qui conditionneront les dimension génie civil des bâtis sur lesquels elles seront posées.

Say one main branch 300 mm dia meter branching off to DN 200 and DN 250 with individual valves to shut off. You need 2 Nos thrust type dismantling joints of sizes DN 200 and DN 250 plus two gate valves of size DN 200 and DN 250 in the chamber. 150 mm spacing between flanges to wall. Hence you need about 2000 x1200 chamber.
