Product Overview

Construction details
Brass body
The brass body prevents the formation of ferrous residues in the
system, thereby helping to prolong the life of the heat generator.
Thermostatic sensor replacement for setting modification
The thermostatic sensor can be easily
removed for maintenance or setting
change.
Temperature gauge holders
The body of the anti-condensation valve
in sizes DN 25 and DN 32 features
temperature gauge holders on the front
and rear sides. The holders allow the
housing of code F29571 temperature
gauges for controlling the working
temperatures of the valve: by-pass water
from the flow line, water returning from
the system and mixed water returning to
the generator.
Hydraulic characteristics
Sizing method / Setting selection
According to the power output and thermal load on the heat
generator, the flow rate provided by the generator can be
calculated. With this value, it’s possible to use the hydraulic
characteristics diagram to obtain the head loss of the valve. The
size is selected by evaluating the compatibility of the obtained
head loss value with the available head of the system pump. The
setting (°C) must be selected so as to guarantee a return
temperature to the generator that is high enough to prevent
condensation, also using the information or instructions supplied by
manufacturers of solid fuel generators.
Installation
The valve can be fitted on both sides of the generator in any
position, vertical or horizontal. Installation is recommended on
the return to the generator in mixing mode; it is also allowed on
the flow from the generator in diverter mode according to the needs
of system control.
