Constructed for efficiency, the Johnson Controls VG2831TM+92NGGA functions as a 3-way electrically-actuated mixing control valve designed to handle various industrial fluid management needs. This unit comes with flat-faced flanged ANSI Class 125 end connections, ensuring reliable integration into existing pipelines. With a weight of 78.0 lbs, this valve maintains a substantial presence that adds to its overall durability.
Measuring 2 1/2 inches, the valve incorporates a 3-way mixing body with a unique spring-return feature, positioning the valve stem upwards with a closed side inlet port. This design enhances the precision in fluid mixing applications. It is equipped with brass trim to foster modified linear flow efficiency. The valve's stroke measures 3/4 inches (19 mm), allowing for sufficient motion to control fluid passage effectively.
For control signal operation, it supports proportional signals of 0-10 Volts DC. Selectable options for current signal types, such as 0-20 mA or 4-20 mA, can be configured using an external field resistor, providing the necessary versatility for different system demands. Designed for a voltage rating of 24 VAC or 24 VDC, the valve can handle an input frequency of 50/60 Hz.
Current consumption is approximately 0.65 Amps during active operation (15.5 VA) and around 0.32 Amps for holding (7.7 VA) at a 24 VAC rating. Its NEMA 2 (IP54) rating offers protection against dust and splashes, making it suitable for most environments.
Temperature tolerances further enhance its functionality, with the actuator able to operate within a range of -40°C to 55°C and withstand storage conditions between -65°C and 85°C. Additionally, the fluid operating temperature can vary between 2°C to 138°C, ensuring adequate performance in diverse situations.
