The V47AR-2 is a temperature-actuated modulating water valve created by Johnson Controls. It is tailored for applications requiring precise water flow regulation to maintain desired heating levels in heat exchangers. The valve measures 1-1/2 inches and features ASME flange connections, ensuring a robust and secure fixture within piping systems.
Designed to operate within an opening point temperature range of 46 to 82 degrees Celsius, the valve acts in direct response to increasing temperatures, enabling it to modulate water flow efficiently. This functionality is critical for effective temperature maintenance in various heating applications. The valve includes a bulb sized at 11/16 x 6 inches, which assists in accurately sensing temperature rises.
The capillary, made of durable nylon armor, extends to a length of 6 feet, facilitating installation in challenging configurations. It has a maximum allowable water temperature threshold of 77°C and is rated for a supply water pressure of up to 150 psig. The inclusion of a standard bypass orifice with a diameter of 0.093 inches enhances its operational capabilities, allowing for controlled flow adjustments. Overall, the V47AR-2 is a critical component for achieving temperature stability in heating processes.
