VG7842NT+74CHGC

The VG7842NT+74CHGC from Johnson Controls serves as a 3-way mixing control valve designed for applications requiring efficient flow management. The valve weighs 7.9 lbs and is structured with a 1-inch body size. Operating at a voltage rating of 24 VAC, it ensures versatility in various systems. This model features a cast bronze body that provides durability, with brass trim for effective sealing.

The valve is designed for NPT threaded end connections, facilitating straightforward integration into existing piping. It has a flow coefficient of 11.6 Cv (10.0 Kv) when operating through Port A (coil), optimizing fluid movement within your systems. The control signal is proportional, allowing for precise adjustments, and the feedback operates within a range of 0(2)-10 Volts DC, enhancing accuracy. Additionally, the model is equipped with two auxiliary switches to provide feedback on its status during operation.

This valve can manage fluid operating temperatures ranging from 2°C to 140°C for water, as well as handling pressures of up to 38 psig for saturated steam, demonstrating its adaptability to varying environmental conditions. The VG7842NT+74CHGC also adheres to ANSI B16.15 Class 250 body ratings, confirming its structural integrity and pressure handling capabilities. With a maximum closeoff pressure of 213 psig (1,468 kPa) and a leakage rating of only 0.01% of maximum flow, the valve maintains efficiency and reliability throughout its operation.
