VBN2
The VBN2 Two-Way Control Ball
Valves control hot and chilled water
with glycol solutions up to 50% in
heating, ventilating, and air
conditioning (HVAC) systems to
provide two-position or modulating
functions. These valve assemblies
can be ordered with or without
factory-mounted non-spring return
or spring return direct-coupled
actuators (DCA).
