V47AS-1C

The Johnson Controls part V47AS-1C is characterized as a temperature-actuated modulating water valve designed with performance in mind. This valve is compatible with 2-inch ASME flanged piping systems. Engineered for precision, it opens as temperatures rise, specifically initiating operation when reaching a minimum of 46°C, and will fully open at a maximum threshold of 71°C. Beyond that, it can handle water temperatures reaching up to 77°C, making it suitable for various heat exchange applications and the regulation of engine-jacket water temperatures.

The valve design includes an effective feature where the bulb can tolerate temperatures up to 11°C above the specified range, ensuring reliable operation under dynamic conditions. Maximum supply water pressure for this valve is rated at 150 psig (equating to 1,034 kPa), which is essential for effective fluid management in industrial applications. The bulb dimensions of this unit measure 11/16 inch in diameter, extending to 10 inches in length, allowing for adequate response to thermal variations.

A 6-foot nylon armored capillary provides resilient performance, contributing to the stability of the valve during operation. The standard bypass orifice diameter measures 0.125 inches, facilitating proper flow characteristics. Constructed with a copper alloy body that contains lead, caution must be exercised as it is unsuitable for potable water applications. Overall, the Johnson Controls V47AS-1C valve is ideal for systems requiring careful temperature management and control in fluid transfer processes.
