Description
The Johnson Controls VA2120-HGA-2 is a proportional Non-Spring Return (NSR) valve actuator designed for fine control in HVAC Applications. This valve actuator accepts a 0-10V control signal suitable for applications that need quiet modulation of the valve This valve actuator is inline mountable making it easy to fit and to integrate in a system. By having a variable voltage control signal from any controller, the actuator then moves the valve to the desired position in proportion with the amount of fluid flow required.
