Description
The Johnson Controls VA9208-AGA-2 Electric Spring Return Valve Actuator is a reliable and universal solution for the regulation of water supply in HVAC systems, particularly in systems that need fail-safe functionality. In floating mode, a continuous signal allows for precise movement of the connected valve, thus improving water flow in the HVAC system. On the other hand, on/off control provides an open or closed signal depending on whether a signal is present or not. The essential characteristic is the spring return actuator, which means that the valve is set to its initial position normally closed in the event of loss of power.
