The VG1845FS+938BAC by Johnson Controls is a robust three-way brass ball valve, engineered for effective flow management. It weighs 16.1 pounds and features connections via threaded NPT, making it suitable for various installation scenarios. Designed with a valve size of 2 inches (DN50), this unit provides a main Cv rating of 46.8 Cv (40.0 Kv), while the bypass port has a Cv of 29.2 Cv (25.0 Kv).
This valve is equipped with an M9216-BAC-2 actuator that operates in an on/off control mode; it utilizes a voltage rating of 120 VAC. The operating capabilities are engineered to handle a maximum pressure of 200 psig (1,378 kPa) at closeoff, which ensures reliable performance in demanding applications. The valve's rangeability exceeds 500:1, allowing for effective adjustments in flow.
The VG1845FS+938BAC is also rated for fluid temperatures ranging from -30 to 140°C, making it versatile for water use within that thermal range. The leakage class for the control port is impressively low at 0.01% of maximum flow, while the bypass port allows for a leakage maximum of 1% of the flow, ensuring high reliability and efficiency during operation. Overall, this valve provides superior control characteristics for fluid handling requirements.
