V47AT-1

The V47AT-1 temperature-actuated modulating water valve from Johnson Controls provides effective regulation of water flow according to temperature variations. Weighing in at 31.15 lbs, this valve is built for durability and is intended for a pipe size of 2-1/2 inches, making it suitable for substantial systems.

Designed for heating applications, the valve operates when the temperature rises at the sensing bulb, which is calibrated to open at points between 115°F and 160°F. The bulb has dimensions of 11/16 inches in diameter and extends 10 inches long, allowing for effective sensing in demanding environments. This valve can handle a maximum bulb temperature of 20°F above the specified range, ensuring resilience during high-temperature conditions.

In terms of water specifications, the maximum water temperature permitted is 170°F, making it vital for various applications where hot water flow is required. Additionally, the valve can accommodate a maximum supply water pressure of 150 psig (1,034 kPa). It includes a nylon-armored capillary, which provides reliable sensor feedback over a standard length of 6 feet, ensuring it can be positioned adequately in many systems.

Replacement components for the valve include the seat repair kit designated STT18A-601R and the sensing element SET29A-632R for ease of maintenance. If needed, an optional bulb well (WEL17A-600R) is available for installation. The valve features an external fitting configured to 1/2-inch NPT for compatibility with standard piping systems.

Commonly utilized in applications such as heat exchangers and temperature regulation for engines, compressors, and hydraulic oils, the V47AT-1 modulating water valve stands out as a reliable choice for efficient temperature management. Overall, its thoughtful design and practical features ensure it performs admirably in various industrial settings.
