The VG1845FS+958BAC is a functional three-way brass ball valve by Johnson Controls, ideal for applications requiring effective flow control. Weighing 16.1 pounds, this valve is constructed to support reliability in various operational settings. With a valve size of 2 inches (DN50), it boasts a robust flow capacity of 46.8 Cv on the main line, catering to significant flow needs, while the bypass port maintains a respectable 29.2 Cv.

Designed with threaded NPT end connections, integration into existing systems is straightforward. The valve operates utilizing the M9216-BAC-2 actuator and accepts an on/off control signal, making it compatible with simple control systems. Its voltage rating is set at 120 VAC, allowing for compatibility with standard electrical setups.

The operational temperature range for the VG1845FS+958BAC is from -30 to 140°C for fluid, supporting various system requirements. The ambient operating minimum can drop to -20°C, enhancing its usability in colder environments. With a maximum closeoff pressure rating of 200 psig (1,378 kPa), this valve reliably maintains system integrity under pressure.

At a remarkable rangeability exceeding 500:1, the valve accommodates flexible flow rates, adapting to various operational requirements. Leakage characteristics indicate a control port leakage of 0.01% of maximum flow and a slightly higher bypass port leakage of 1%, indicating excellent efficiency during operation. Overall, the VG1845FS+958BAC is engineered for precision and durability, making it an ideal choice for complex fluid control scenarios.
