Description
The Johnson Controls JG24A020 Electric Zone Valve Actuator is a trustworthy one to be used for accurate control of water flow in systems with high temperatures in HVAC. This means that water is free to flow through the zone when power is on. When a 24V AC signal is applied, the actuator stays in position and thus facilitates constant water circulation. The N/O design means that the valve will stay open in the absence of supply voltage, which might be useful in some high temperature applications where a valve would help in preventing too much heating.
