The V47AR-2C from Johnson Controls is specifically designed as a temperature-actuated modulating water valve. This component activates to open when there is a rise in temperature, serving an essential role in maintaining optimal heating conditions. It features a 1-1/2 inch pipe size with ASME flange connections for robust installation.
The valve utilizes a Style 4 immersion bulb, measuring 11/16 inches in diameter and 6 inches in length, enhancing its sensitivity to temperature changes. It operates effectively with an opening point temperature range between 46°C and 82°C (115°F to 180°F) to facilitate heating applications. Furthermore, the maximum temperature for the bulb can reach 11°C above the specified operational range.
The maximum allowable water temperature through this valve is capped at 77°C, while the valve's design can handle supply pressures of up to 150 psig (1,034 kPa). To ensure proper functioning, the standard bypass orifice diameter is maintained at 0.093 inches.
For installation convenience, a 6-foot nylon-armored capillary tube is included, offering robustness and flexibility in placements. Should maintenance be required, a seat repair kit (part number STT17A-610R) is available, and users can replace the sensing element with a part designated as SET29A-629R. An optional bulb well (part number WEL17A-601R) can also be utilized to enhance system integration. Overall, the V47AR-2C provides reliable performance in applications requiring precise temperature modulation.
