Description
The Johnson Controls VA-4233-GGC-2 Proportional Valve Actuator is a well-built part that is designed to control proportional valves of HVAC systems. Where precise control of the valve opening is required to generate the suitable flow rates of the fluids, it can be used and it is electrically controlled by a 24V power source. This actuator has a 2-switch type design where the stroke is proportional to the flow rate needed in the system, thus allowing for easy flow rate adjustment. In HVAC systems, this actuator is normally applied to valve the fluid like water or glycol for heating or cooling.
