Johnson Controls V47AR-3 Valve

The Johnson Controls V47AR-3 is a rugged, 1-1/2 inch ASME flange direct-acting temperature actuated water regulating valve engineered for demanding hydronic and process cooling applications. This cast iron water valve is designed to modulate water flow through a heat exchanger to maintain a specific temperature setpoint between 160°F and 230°F. Equipped with a 6-foot capillary and a Style 4 sensing bulb (11/16" diameter x 6" length), it utilizes a 1/2" NPT external fitting for secure installation. This specific model is a direct equivalent to the V47AR-3C, ensuring seamless integration into existing commercial HVAC systems. The direct acting mechanism opens the valve on a temperature rise, making it an essential component for high-temperature fluid regulation where precision and reliability are mandatory for system stability. Its heavy-duty construction minimizes maintenance requirements in high-torque environments.

Key Benefits

• Precise Thermal Modulation: Features a wide 160 to 230 degrees F range suitable for heavy-duty industrial heating and high-temperature cooling loops.
• Durable Construction: The cast iron body and ASME flange connection ensure structural integrity under the high pressure and vibration profiles typical of mechanical rooms.
• Flexible Installation: The 6-foot copper capillary allows for remote mounting of the valve body while positioning the Style 4 sensing bulb directly in the fluid stream.
• Field Interchangeability: This unit is functionally identical to the Johnson Controls V47AR-3C, streamlining part replacement protocols.
• Self-Contained Power: Operates without the need for an external power source or controller, utilizing the pressure of the fluid in the capillary for actuation.

Common Questions

What is the difference between the V47AR-3 and V47AR-3C?
There is no functional or dimensional difference between these two models; the V47AR-3 is identical to the V47AR-3C and can be used as a direct replacement in all valid applications.

What connection type does this valve use?
This valve features a 1-1/2 inch ASME flange, which is the standard for high-flow commercial piping, ensuring a leak-proof seal compared to standard threaded connections.

Does this valve open or close as the temperature increases?
As a direct acting valve, the V47AR-3 is designed to open on a temperature rise, increasing flow to the cooling medium or heat exchanger as the sensed temperature exceeds the setpoint.
