Description

These 2-position (open/close) control actuators are used with VCZ1000, 1100, 6000 and 6100 series hydronic valves in a normal indoor environment to provide quick opening/closing to control the flow of hot and/or chilled water or glycol solution to 60% concentration. They are designed for on-off “zone” control of heating/cooling systems, or to control individual fan coil, baseboard radiator or convector applications.

Depending on the model selected, the actuator can be controlled by a low or line voltage SPST or SPDT controller, such as a room thermostat, aquastat or flow switch.

VC80 series valve actuators are designed to be used with hardwired electronic thermostats with series anticipator or powerstealing thermostats. Recommended control thermostats include T8601D, T8401C,T8380 and T8360 families.

VC actuators use cam-operated cartridge travel to resist water hammer. Internal limit switches prevent motor overrun.
