The Johnson Controls VG2831UM292NGGA is an electrically-actuated mixing valve that enables effective mixing of fluids. This valve is classified as a 3-way flanged globe valve, featuring end connections compliant with Class 125 ANSI standards. It has a significant weight of 97.0 lbs, making it a robust part for demanding applications. Designed to operate at a voltage of 24V AC/DC, the valve can handle an input frequency of either 50 or 60 Hz, allowing for compatibility in varying electrical setups.
Durability is enhanced by its NEMA 2 (IP54) rating, providing a level of protection against intrusion of solids and moisture. The valve's fluid handling capabilities span from 2°C to 138°C, accommodating a wide range of operational scenarios. Additionally, the actuator's storage temperature tolerance ranges from -65°C to 85°C, enabling safe storage under extreme conditions.
The humidity tolerance extends from 0% to 90% RH without condensation, furthering its applicability in humid environments. The housing is finished in black aluminum, providing a combination of durability and aesthetic suitability. The current draw is specified at 15.5 VA while running and 7.7 VA when holding under 24 VAC supply.
The VG2831UM292NGGA features a substantial flow capability with a flow coefficient of Cv 74 and Kv 63.4, which ensures efficient mix operations. Its brass trim permits a modified linear flow characteristic, promoting accurate flow control throughout its operation. This valve is an excellent choice for applications requiring precise fluid mixing and environmental resilience.
