Multiway valve with cartridge and fluid mechanics inserts

A multiway valve comprising:

• a generally cylindrical shaped hollow valve body having at least one handling opening;
• a plurality of through openings made on the outer wall of said valve body and defining a first group of connecting openings and a second group of connecting openings;
• a generally tubular shaped handling element or cartridge pivotally disposed in said valve body and comprising at least two first through radial openings made on the outer wall of the cartridge itself;
• at least one device for statically/dynamically adjusting and balancing flow rate;
• wherein the at least one device is attached in a fluid communication to at least one of said connecting openings;
• wherein the handling element or cartridge comprises at least one tubular shaped fluid mechanics insert coaxially housed inside said cartridge, having a second radial opening adapted to control the fluid passage;
• wherein said fluid mechanics insert comprises a cell formed inside the cavity of the fluid mechanics insert itself to define a homogeneous fluid passage in order to maximize the fluid mechanics efficiency of the multiway valve itself;
