VG7842GT+74CHGA

The VG7842GT+74CHGA model from the VG7000 Series produced by Johnson Controls represents an efficient three-way mixing control valve. Constructed from cast bronze, the valve exhibits strong build quality and reliability. It is designed for installations where size limitations are essential, with a valve size of 1/2 inch (DN15).

The valve operates with a Cv factor of 4.6 (or 4.0 Kv), making it suitable for various fluid control needs. Its trim is made of brass, enhancing durability and performance in harsh conditions. Featuring NPT threaded end connections, this unit can be integrated into existing piping with ease.

At the core of its design is the actuator model VA7830-HGA-2, which facilitates proportional control, ensuring precise regulation of flow. This actuator can produce an impressive minimum stem force output of 180 lb. The VG7842GT+74CHGA valve is also rated IP54, which provides protection from dust and splashing water, making it appropriate for various industrial applications.

Liquid temperature capabilities range from 2 °C to 140 °C, while the valve itself maintains a temperature operating range of 2 °C to 65 °C. The exceptional rangeability of greater than 100:1 allows for fine-tuned flow adjustments, achieving optimal system performance. Furthermore, the valve ensures minimal leakage at a rating of just 0.01% of maximum flow, which contributes to its efficiency and effectiveness in applications requiring stringent control.
