Single-pipe manual valves
Manual single-pipe valves, as opposed to the thermostatic type, do not allow choking of the flow to the heating element: in the open position, all the ring flow passes through the radiator;
in the closed position, the heating body is completely isolated and all the fluid is bypassed on return.
Flow input and output can be inverted with items VM 1405 and VM 1415.
Items VM 1505 and VM 1515 with external vertical feed allow the flow input to be changed using the appropriate probes contained in the kit.
