Note
Valves are furnished standard with right inlets.
Proceed as follows whenever it is necessary to invert the inlet:
1) remove the manual lever and the metal label
2) remove the valve cover and extract the internal rotor
3) rotate the internal aluminium bush 180° so that the profiled
path is positioned at the opposite side
4) reinstall the internal rotor in the same position
5) reinstall the metal label upside down from its previous position
6) The valve must be installed in the plumbing circuit according to the flow direction specified on the valve.
Main characteristics
Mut valves are made with cast-iron bodies and internal rotors. Rotor rotation angle is about 90°. Mixing is done by a circular segment rotor in models VDM and by a butterfly valve in models VM. Mut valves are furnished with manual controls but can be easily motorised using motors and valve-motor connections marketed by manufacturers of regulation components.
