Johnson Controls VG7243LT+72CHGA Valve Assembly

The Johnson Controls VG7243LT+72CHGA is a performance-grade 2-way normally open globe valve assembly designed for precise modulation in commercial HVACR systems. Built with a rugged 3/4 inch NPT cast bronze body and stainless steel trim, this assembly is engineered to handle hot water, chilled water, and steam applications with a 7.3 Cv flow coefficient. The integrated VA7820 series electric actuator provides flexible control options, featuring field-selectable 0-10 VDC, 4-20 mA, floating, or two-position signaling. Its spring return safety mechanism ensures the valve returns to the open position upon power loss, protecting critical equipment and maintaining system flow. With equal percentage flow characteristics, this proportional control valve delivers stable temperature regulation and superior rangeability for demanding hydronic loops.

• High-Durability Construction: Features a cast bronze body and stainless steel stem and plug to resist corrosion and extend service life in steam and glycol environments.
• Universal Field Control: The 24VAC actuator supports multiple input signals, allowing technicians to match existing controller outputs without additional hardware.
• Fail-Safe Operation: Mechanical spring return functionality ensures a reliable "normally open" default state during power interruptions.
• Precision Metering: The equal percentage flow design provides linear heat output across the full stroke of the valve for optimized energy efficiency.
• Ease of Integration: Standard NPT threaded connections and a compact footprint simplify installation in tight mechanical rooms and terminal unit cabinets.

What is the maximum fluid temperature for this assembly?
This VG7000 series valve is rated for fluid temperatures ranging from 35°F to 284°F, making it suitable for both chilled water and low-pressure steam applications.

Can the control signal be changed after installation?
Yes, the 72CHGA actuator features internal DIP switches that allow you to field-select between proportional (0-10V/4-20mA) and floating/on-off control modes.

Is this valve suitable for domestic potable water?
No, this assembly is designed specifically for closed-loop HVACR systems and low-pressure steam; it should not be used in drinking water applications due to material specifications.
