VBF2
The VBF2 Two-Way Ball Valve
Assemblies, with and without
actuators, 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).
