Johnson Controls V47AC-29 Valve

The Johnson Controls V47AC-29 is a heavy-duty temperature actuated modulating water valve designed for precision flow control in commercial refrigeration and HVAC systems. Featuring a 3/4 inch NPT connection, this valve is engineered to regulate the flow of water or glycol to maintain constant temperature setpoints. It operates within a 115-180 degree F range, making it ideal for high-temperature applications where consistent thermal management is critical. The unit includes a 11/16" x 3 1/4" sensing bulb with a 6-foot capillary, providing rapid response to temperature fluctuations. This model is identical to the V47AC-29C, ensuring direct compatibility for technicians replacing legacy Penn or Johnson Controls hardware. Built with a rugged brass body and corrosion-resistant internal components, the V47AC-29 is a reliable solution for condenser water regulation and process cooling loops where a modulating water valve is required to optimize head pressure and system efficiency.

Key Technical Benefits

• Precise Modulation: Provides accurate throttling of water flow to maintain desired temperatures in demanding HVACR environments.
• Broad Temperature Range: The 115 to 180 degree setpoint range accommodates specialized high-heat applications.
• Interchangeable Design: Full compatibility as the V47AC-29C replacement allows for seamless field installation without piping modifications.
• Durable Construction: High-quality bellows and seat materials resist scaling and ensure long-term performance in open or closed loops.
• Versatile Application: Suitable for use with non-corrosive refrigerants and standard water-cooled condensers.

Common Questions

What is the difference between the V47AC-29 and V47AC-29C?
There is no functional or physical difference; the V47AC-29 is identical to the V47AC-29C and serves as a direct drop-in replacement.

Can this valve be used for steam applications?
The V47 series is designed specifically as a water-regulating valve; always verify media compatibility with the brass and internal rubber components before installation.

How do I adjust the temperature setpoint?
Adjustments are made via the range screw located at the top of the valve housing, which alters the spring tension against the bellows for precise calibration.
