The VG2431UM+845C00 from Johnson Controls represents a reliable pneumatic solution in the VG2000 series of globe valves. This particular model functions as a 2-way valve, allowing control over fluid flow. Weighing in at 90 lbs and sized at 3 inches, it provides robust construction suitable for varied operational environments. Its body is crafted from cast iron, ensuring durability and compliance with ASME B16.1, Class 125 standards.

The valve is designed to operate under a temperature spectrum from 2°C to 138°C for fluids. When dealing with water, it can tolerate a maximum pressure of 175 psig at a temperature of 66°C and 125 psig at its higher limit of 138°C. For steam applications, it has an allowable pressure of 35 psig at saturated conditions (241 kPa) when at 138°C. The flow characteristic is modified linear, optimizing flow control for enhanced performance.

Key components of the valve are manufactured from resilient materials that contribute to its longevity. The stem is constructed from 316 stainless steel, providing excellent corrosion resistance, while the plug is made of brass. The spring range for this actuator is set between 3 to 7 psig, with a closeoff pressure of 17 psig, ensuring reliable sealing and operational integrity.
