MIXING VALVE ACTUATOR
The Actuator is designed to provide electronic
temperature control for Viega's Mixing Valves
in heating, cooling and snow-ice melting
applications. The actuator is designed to fit and
modulate all of Viega's Mixing Valves 3/4" - 2".
Operated by a 24V signal from the Viega Basic
Heating Control, Advanced Heating Control
and Advanced Snow Melt Control.

FOUR WAY MIXING VALVES
Four-way mixing valves regulate supply fluid
temperature to the system and the return fluid
temperature to the source. Four-way valves
can be used in heating, cooling, snow and ice
melting applications. These valves can be
controlled manually or automatically. To
properly protect the heat source from flue gas
condensation the four way mixing valve must
use actuator (stock code 20042).

THREE WAY MIXING VALVES
Three way mixing valves regulate fluid
temperature to the system from the source.
These valves are ideal for mixing or diverting
fluid to control temperature in heating, cooling,
and snow-ice melting system applications. The
valves can be controlled both maually or
automatically with the use of an actuator (stock
code 20042).

NON-ELECTRIC OUTDOOR RESET
CONTROL
This modulating valve control fits both Stations
and Diverting Valves. Control modulates
system water temperature based upon outdoor
temperature and the selected ratio setting.
Capillary length 32 feet from valve to outdoor
sensor (6-1/2 feet from supply sensor to
actuator; 6-1/2 feet from actuator to ratio
adjuster; 26 feet from ratio adjuster to outdoor
sensor).
