The VG1845FS+948GGA from Johnson Controls is classified as a 3-way brass ball valve, designed for precise fluid regulation. Constructed with threaded NPT connections, it weighs 16.1 lbs and has a size of 2 inches. The control port achieves a flow coefficient (Cv) rating of 46.8, while the bypass port is rated at 29.2 Cv. This configuration allows for efficient fluid diversion and distribution.

For flow characteristics, this valve operates with equal percentage control for the in-line port A and a linear response for the angle port B. It utilizes an M9216-GGA-2 actuator that allows proportional control, ensuring that the flow can be finely adjusted based on system demands. The valve operates effectively at a voltage rating of 24 VAC, making it suitable for a range of applications.

Operating conditions are versatile; the VG1845FS+948GGA can handle ambient temperatures as low as -30°C and maximum closeoff pressure can reach 200 psig (1,378 kPa). Its fluid temperature range extends from -30°C to 140°C, making it adaptable for various media. The overall performance integrity is demonstrated by a rangeability of more than 500:1, making this valve capable of operating under widely varying flow conditions while maintaining control.

For leakage, the control port meets very stringent criteria with only 0.01% of max flow leakage, whereas the bypass port allows for a maximum of 1%. This ensures minimal loss and maximum efficiency in systems where this valve may be employed.
