The quick connection allows the extremely fast creation of manifolds (without the need for tools or interposed sealing elements) with a high flow rate and multiple outlets on the basis of the worksite requirements. The use of modular manifolds also means that warehouse stock can be limited to just two components: R53SM intermediate module and R53ST pair of end modules. R53SM R53ST

The loss of pressure indicated in the diagram refer to the single connection when the number of lockshield opening turns is varied.  NOTE. The variation in water temperature and hence in its density implies pressure drop swings of about ± 1 % (for the same water flow rate); this figure is not significant for calculation purposes.  Main features The R53SM e R53ST modules with quick connection are made via the hot moulding method that produces smaller dimensions and thicknesses with notable transit sections for the fluids and hence limited pressure loss and flow noise. The flow rate is regulated by means of a micrometric lockshield with mechanical memory, that can intercept the flow for maintenance purposes and then easily restore the initial operating conditions. The modules are manually assembled and the hydraulic seal is guaranteed by the pre-assembled O-Rings. The R53SM modules are connected to the other components (valves, cocks, pipes, etc.) by interposing the two R53ST end modules with female thread.

The operation is extremely simple and doesn’t require any tools, but it’s important to check that the end parts are clean and free of impurities, and to lightly lubricate the O-Ring with silicone grease if necessary. To enable the quick connection of the individual modules, position them side by side with their vertical axes rotated by 90° in relation to each other. Push lightly in the axial direction until they reach their end stop, then rotate the two modules by 90° so that the male and female parts of the quick connection are in line with each other. To assemble a distribution manifold is necessary a pair of R53ST end modules and the right number of R53SM intermediate modules for the number of outlets required. The modules assembled can be of different types (it is even possible to connect different manifold models), but they must necessarily have a nominal diameter of DN32.  NOTA. For example, to create a 5-outlets modular manifold, you will need a pair of R53ST end modules plus three R53SM intermediate modules. For a manifold with just two outlets, the pair of R53ST end modules is enough. The modules with quick connection are assembled with the other components thanks to the R53ST end modules with threads, available in the size 1” and 1-1/ 4”. The grip with spanners (needed to tighten the male threads to the end modules) should be made using the special flat seats on the modules. Do not apply a torsion or crushing strain on the modules, to avoid creating deformations that could make them unsuitable for assembly or prejudice the hydraulic seal. After assembling the DN32 manifolds with the required number of outlets, they can be installed into the cabinets or on the wall. Once the manifolds have been installed and the primary supply lines have been hooked up, is possible to connect the circuits using suitable adaptors. Known the flow rate that must pass through the circuits connected to the manifold, with circulator operating and any interceptions on the return manifold kept open, remove the protection cap on the front of the modules and then use the R558 key to completely loosen the mechanical memories and lockshields. Starting from the fully closed position, tighten the lockshields of the modules until the required flow rate in the various circuits is reach. Once the regulation is complete, tighten the mechanical memories as far as they will go, then reassemble the protection caps.  Regulation  NOTA. If you are unable to obtain the designed flow rates for all the circuits, make sure the circulator size is correct and the manifold receives the necessary flow rate and pressure.
