The VG1841FT+938BGC by Johnson Controls is designed as a three-way ball valve, ideal for regulating fluid flow within diverse operational settings. Featuring a sturdy forged brass body, this valve has a size of 2 inches (DN50) and is engineered for reliability. Its Cv factors are rated at 73.7 Cv for coil applications and 36.8 Cv for bypass paths, highlighting its effective flow capacity.

In terms of materials, the valve incorporates a chrome-plated brass ball and a nickel-plated brass stem, designed to withstand corrosion and wear over time. The end connection is NPT threaded, allowing easy integration into piping systems. This model utilizes the actuator VA9208-BGC-3, known for its spring return mechanism, enabling swift operational response with port A in a counterclockwise direction when opened.

The maximum closeoff pressure for the VG1841FT+938BGC reaches 200 psig (1378 kPa), while it can handle a maximum operating pressure drop of 50 psid (340 kPa). With a rangeability exceeding 500:1, this valve provides excellent control over varying flow conditions. The leakage ratings ensure minimal loss; the control port is rated at 0.01% of maximum flow, while the bypass port allows for up to 1% of maximum flow leakage.

This valve effectively operates within a fluid temperature range from -5 to 95 °C, making it well-suited for different environmental conditions in industrial applications. Overall, the VG1841FT+938BGC is a reliable and efficient component for any system requiring precise fluid management.
