APPLICATION

The VC7900 Series Modulating Control Valves provide
optimum control of hot and/or chilled water flow in various
heating and cooling applications.
The VC hydronic valve consists of a valve body and
replaceable characterized cartridge assembly. When used with
a Honeywell VC7900 actuator, the valve provides proportional
flow in either diverting or mixing applications. They are
designed to provide sinusoidal valve actuator travel, and
therefore operate silently and resist water hammer. The
VC7900 series valve actuator is used with any 0-10 Vdc
controller.
