The VG2831VM+916AGA model from Johnson Controls is categorized as a 3-way electrically-actuated mixing flanged globe valve. This valve is constructed to meet high standards, with a body rating compliant with ASME B16.1, Class 125. Weighing in at 116 pounds, it is built for robustness and reliability in various operational conditions.
Designed for operation with a voltage of 24V AC/DC, this valve supports 50/60 Hz frequency input. The operational fluid temperature ranges from 2°C to 138°C, which makes it suitable for various heating and cooling applications. In terms of humidity tolerance, the device can operate in conditions that reach up to 90% relative humidity, provided that there is no condensation. Additionally, the actuator has a specified storage temperature range that spans from -40°C to 86°C.
The valve features 4-inch end connections, utilizing Class 125 ANSI flat-faced flanged connections for ease of integration into piping systems. With a flow coefficient of Cv 131 and Kv 112.3, this valve ensures effective control over fluid flow. The internal trim comprises brass, combined with a modified linear flow characteristic, optimizing its performance.
The actuator's minimum current rating requirements are essential, with a 6.5 VA supply required for AGx models and 7.5 VA for other designs. Its typical housing color is black, contributing to both its professional appearance and functionality. With an IP rating of NEMA 2 and IP42, this valve is designed for suitable protection against various environmental factors.
