TYPE OF SOLENOID VALVE

In a hydraulic system the zones are built up physically

using solenoid valves. Each zone can thus be

managed independently by controlling the individual

solenoid valves.

2 types of solenoid valves are used in the systems:

• ON/OFF, which requires an ON/OFF contact

• Open/Close, which requires an Open/Close contact

PLACING THE SOLENOID VALVES

In heating systems the typical installations has all the

solenoid valves positioned on the collector, grouped

in a box in the boiler room. In dwellings on several

ﬂ oors this solution can be replicated for each ﬂ oor.

In fan-coil systems the solenoid valve can be installed

inside the fan-coil itself.

In 2-tube systems there is just one solenoid valve

for both the heating and cooling functions. In 4-tube

systems there are 2 solenoid valves, one each for the

heating and cooling functions.
