V47AS-1

The Johnson Controls V47AS-1 is a temperature-actuated modulating water valve. This unit is sized at 2 inches, suitable for various heating applications. Designed to open in response to increases in temperature, it operates effectively within a range of 46°C to 71°C (115°F to 160°F). This functionality makes it an essential component for regulating water or glycol flow to achieve and sustain desired system temperatures.

The valve includes a standard bypass orifice with a diameter of 0.125 inches, facilitating measured flow control. Additionally, it features a nylon armored capillary that extends 6 feet, classified as Style 4, providing adaptability in installation height and distance. The maximum bulb temperature is about 11°C (20°F) above the maximum operation threshold, ensuring that it can accommodate slight variations in operational conditions without failure.

For media types, the maximum temperature tolerance is set at 77°C, ensuring the valve maintains performance in hot fluid environments. Furthermore, it can handle a maximum supply water pressure of 150 psig (1,034 kPa), making it robust enough for high-pressure systems. The end connection is designed with an ASME flange type for secure integration into existing setups. In summary, the V47AS-1 is engineered to effectively manage temperature regulation in heating systems through precise fluid control.
