R53MM-R53MT

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

Description
The modular manifolds with bayonet connection R53MM and R53MT,equipped with a flow rate measurer and balancing lockshield valve with
mechanical memory, 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 balancing and a flow rate check with direct measurement for the individual circuits. The innovative solution of the 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: R53MM intermediate module and R53MT pair of end modules.

Characteristics
The R53MM e R53MT 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 flow rate measurer with a scale from 0,5 l/min to 5 l/min. The flow rate is regulated by means of a micrometric lockshield valve with mechanical memory and centesimal calibration of the transit surfaces. The R53MM and R53MT modules must only be used for delivery manifolds, so that the water flow towards the circuits strikes the measurement plate, keeping the measurer spring compressed. 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 two R53MM intermediate modules with the components (valves, taps, pipes, etc.) is made with the two R53MT end modules with their female thread - available in the two measurements 1” and 1 1/4". The external structure of the R53MT end modules ensures the easy assembly of the components using just a spanner, without applying any strain on the already-assembled modules. The R53MM and R53MT modules are fitted with base 18 adapter connections for connecting the distribution pipes.
