Honeywell VC7931

The VC7900 Series Modulating Control Valves provide precision flow control of hot or chilled water 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 modulating, 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 or 2-10Vdc
controller.
