Johnson Controls V47AT-1 Valve

The Johnson Controls V47AT-1 is a high-capacity temperature actuated water regulating valve specifically engineered for demanding HVACR and industrial fluid applications. This 2-1/2 inch ASME flange valve features a heavy-duty cast iron direct acting body, ensuring maximum structural integrity and corrosion resistance in commercial piping environments. Operating within a precise heating point range of 115 to 160 degrees F, the assembly utilizes a 6-foot capillary connected to a high-sensitivity Style 4 bulb—measuring 11/16-inch in diameter and 10 inches in length—to provide accurate thermal modulation. As a professional-grade component, this model is technically identical to the V47AT-1C, offering a seamless drop-in replacement for existing water-cooled condensers or heat exchange loops. The inclusion of a 1/2 inch NPT external fitting for the sensing element ensures secure installation within standard immersion wells. By modulating flow based on temperature rise, the V47AT-1 maintains critical system equilibrium and head pressure without requiring external power or electronic actuators.

• Robust Flanged Connection: The 2-1/2 inch ASME flanged ports provide secure, leak-resistant installation for high-flow industrial liquid lines.
• Mechanical Reliability: Direct-acting design utilizes thermal expansion for throttle control, eliminating the need for electrical wiring at the valve.
• Broad Compatibility: Fully interchangeable with V47AT-1C specifications, making it a versatile stock item for facility maintenance.
• Industrial Sensing Bulb: The 10-inch Style 4 bulb provides a large surface area for rapid response to fluctuating fluid temperatures.

Common Questions
