The VG1845FS+928GGA by Johnson Controls is a solidly built 3-way brass ball valve, engineered for demanding industrial applications. This component features threaded NPT end connections for straightforward installation, with a total weight of 16.1 lbs. Designed with a 2-inch connection size, the valve allows for substantial fluid flow, coupled with a control port Cv of 46.8 (40.0 Kv). The bypass port offers a Cv of 29.2 (25.0 Kv), enabling efficient operation under varying conditions.
In terms of operational characteristics, the valve supports an equal percentage flow for the in-line port A or coil, while the bypass angle port B operates on a linear flow basis. This duality increases the valve's adaptability across various fluid control scenarios. The actuator for the VG1845FS+928GGA is the M9216-GGA-2, which facilitates precise modulation through a proportional control signal, powered by a 24 VAC supply.
The valve excels in a wide temperature spectrum, rated from -30°C to 140°C, making it suitable for diverse fluids, including water. The construction allows it to handle a maximum closeoff pressure of 200 psig (1,378 kPa), providing security in pressurized systems. Additionally, the leakage class is remarkably low, at 0.01% of the maximum flow for the control port and 1% of the maximum flow for the bypass port, ensuring operational efficiency.
With a rangeability of greater than 500:1, the VG1845FS+928GGA is designed for precise fluid management, allowing it to perform efficiently under a variety of conditions and demands. Whether used for water or other compatible fluids, this valve provides flexibility and performance across a myriad of applications.
