HONEYWELL VC7931 MOTORISED CONTROL VALVE
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.
Honeywell VC Series balanced 2-position hydronic valves are used in domestic and small commercial heating and cooling applications to control the flow of hot and/or cold water.
They consist of an actuator, valve and a cartridge assembly 2-way valves are designed for on-off zone control of domestic systems.
3-way valves can be piped for either diverting or mixing valve applications in domestic central heating and/or cooling systems.
Both versions can be used to control individual fan coil, radiator, space heater or convector applications. Depending on the model selected they can be controlled by a low or line voltage SPST or SPDT controller such as a room thermostat, aquastat or flow switch.
VC Series hydronic valves are designed to take advantage of sinusoidal valve actuator travel, and therefore operate silently and reduce water hammer. Through internal logic, the actuator only takes power while driving the valve to the commanded position.
The actuator head is removable without affecting the integrity of the water system. All actuator versions are interchangeable with any valve body, offering the highest flexibility for boiler production line assembly, and maintenance.
The valve piston construction allows for port sealing that is independent of the differential pressure across the valve. Flow through the 2-way valve can be in either direction, so the ports are not designated. 3-way valves are suitable AB to A or B, and from A or B to AB
