R53VM-R53VT

Modular manifold and Pair of end manifold DN32, with bayonet connection

Description
The modular manifolds with bayonet connection R53VM and R53VT, equipped with a thermostat-controlled valve, are designed for systems
distributing hot water for heating and cold water for air-conditioning, with the aim of simplifying and speeding up installation. The result is a highly
flexible product that's practical, attractive and ergonomic. They are widely used in radiant panel distribution and in radiator distribution requiring
the interception of the individual circuits and their thermoregulation. The innovative solution of the single module with bayonet connection allows the
extremely quick creation (without the need for tools or interposed sealing elements) of manifolds with a high water flow rate and multiple connections
on the basis of the worksite requirements. The use of modular manifolds also means that warehouse stock can be limited to just two components: R53VM
intermediate module and R53VT pair of end modules.

Characteristics
The R53VM e R53VT modules with bayonet 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. They take a bonnet with an AISI304 stainless steel cantilever rod
that removes any obstacles in the fluid's path, thereby reducing the level of turbulence. The R53VM and R53VT modules should preferably be used for
return manifolds so that the flow of water from the circuits strikes the disc of the bonnet from the front, keeping it in contact with the thrust pin of the
manual handwheel or the electro-thermal heads and avoiding vibrations or detachments in the event of notable differential pressure levels. Thanks to
the special bayonet profile, the modules are manually assembled and the hydraulic seal is guaranteed by the pre-assembled O-rings. The connection of
the R53VM intermediate modules with the components (valves, taps, pipes, etc.) is made with the two R53VT end modules with their female thread -
available in the two measurements 1” and 1 1/4". The external structure of the R53VT end modules ensures the easy assembly of the components using just
a spanner, without applying any strain on the already-assembled modules. The R53VM and R53VT modules are fitted with base 18 adapter connections
for connecting the distribution pipes.
