The cutaway models illustrate commercial components used for drinking water and gas plumbing, such as shut-off fittings, backflow prevention valves and volumetric totalisers.
The location of the cuts allow the design details to be clearly seen.
The models are clearly laid out on display panels or base plates.
A short description and a sectional view are included, so the models can also be used for technical drawing exercises.
