What it is
The Caleffi Multibloc is a cold water inlet control valve assembly used on unvented hot water cylinders, combining pressure reducing valve function within the inlet control group. It is supplied for the Popular Cylinder range of cylinder spares and is rated at 3/6 bar with push fit connections. The valve regulates incoming mains pressure to the cylinder and forms part of the cold water inlet control set.
