The Johnson Controls VG2231UM+845D00 is a pneumatically-actuated 2-way globe valve engineered for effective control of fluid flow. Weighing 80.0 lbs, this valve is designed in accordance with ASME B16.1 Class 125 specifications, providing structural integrity and reliability. It has a valve size of 3 inches, enabling it to manage significant flow rates efficiently.

This valve operates effectively within a fluid temperature spectrum from 2°C to 138°C. Regarding pressure capabilities, it supports a maximum allowable pressure of 175 psig when handling water at 66°C, while it can sustain up to 125 psig at 138°C. For steam applications, the VG2231UM+845D00 accommodates a maximum saturated steam pressure of 35 psig (241 kPa) at 138°C.

The design features include a modified linear flow characteristic, which enhances fluid regulation. Constructed with a sturdy cast iron body, the valve utilizes 316 stainless steel for the stem, ensuring durability and resistance to corrosion. Meanwhile, the plug is made from brass, contributing to the overall efficiency of the system. The spring operates within a range of 4 to 8 psig and has a closeoff pressure rating of 70 psig, enabling reliable sealing and performance under varying operational conditions. This makes the VG2231UM+845D00 a versatile choice in numerous industrial applications.
