Description
The Johnson Controls JH13A020 Electric Zone Valve HCO Actuator is an effective device in the HVAC systems that control the flow of water in the zones that are required. This tiny unit has a normally closed spring-return mechanism. This type of valve is closed and does not allow the water to pass through the zone that the valve has been installed to control. The spring-return mechanism guarantees, therefore, that the valve closes as soon as possible, thus restricting the water and flood supply. This fail-safe design makes the JH13A020 ideal for use in applications that must have a positive shut-off.
