The Johnson Controls VG7842RT+3008DP is a three-way mixing control valve, specifically designed for efficient fluid flow management. This valve operates with an end connection type of NPT, allowing for secure integration into various systems. Weighing approximately 12.1 lbs, it is a robust component suitable for various operational environments.

With a size of 1-1/2 inches, the VG7842RT+3008DP maintains a flow coefficient of 28.9 Cv, which supports effective mixing and control of flow in a range of applications. The valve body is made from cast bronze, ensuring durability and resistance to corrosion, while the trim material is brass, which enhances the valve's effectiveness in diverse conditions.

Equipped with a pneumatic actuator model V-3000-8012, which is openly mounted, this valve includes a V-9502 positioner for precise control. The actuator's effective area spans 8 square inches and operates efficiently within a spring range of 4 to 8 psig. This combination ensures accurate valve positioning during operation.

Furthermore, the body of the valve meets ANSI B16.15 Class 250 ratings, illustrating its capability to handle significant pressures. The valve can operate with fluids across a wide temperature range, from 2°C to 140°C, and is designed to support a maximum recommended pressure drop of 30 psig. Its exceptional flow rangeability exceeds 100:1, enabling versatile applications without compromising performance. Lastly, the leakage rate is remarkably low at just 0.01% of the maximum flow, making this valve a highly efficient option for control applications.
