Features
Modulating valve package
The control valve is modulating
depending on the 24V triac signal
from the controller, which
determines the valve position by a
control algorithm. If the valve loses
power, the valve returns to the close
position. Valve packages are factory-
mounted and leak-tested at 13 bar.
Depending on the application, a 2-
way or a 3-way/4-port valve is
available.
