Damper Applications Guide: Constant Volume Damper and Actuator Characteristics

From Belimo Americas
 

 

The economizer portion of an air-handling system is not only responsible for reducing the operating cost of the system, but more importantly, it has to provide a sufficient volume of outside air at all times to ensure good indoor air quality. The function of the economizer also affects the pressurization of the building. A slight positive pressure is needed to prevent infiltration of unconditioned outside air.

Products & Services
Valve actuators mount on valves and, in response to a signal, move a valve to a desired position using an outside power source. Search by Specification | Learn more about Valve Actuators
Electric valve actuators mount on valves which, in response to a signal, automatically move to a desired position using an outside power source. Single-phase or three-phase AC or DC motors drive a combination of gears to generate the desired torque level. Search by Specification | Learn more about Electric Valve Actuators
Pneumatic valve actuators adjust valve position by converting air pressure into linear or rotary motion. Search by Specification | Learn more about Pneumatic Valve Actuators
