These 2-position (open/close) control actuators are used with VCZ 1000, 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 VAC age SPST or SPDT controller, such as a room thermostat, aquastat or flow switch.

• Double insulated actuator
• Quick and easy replacement of moving parts
• Actuator head installation does not require draining the system
• Selectable/switchable electronic fail safe normally open or normally closed
• Self alignment shaft adapter
• SPST control signal
