Designed for pneumatic applications, the VG2231UM+845E01 is a globe control valve manufactured by Johnson Controls. Its 2-way operation relies on a push-down-to-close mechanism, facilitating control over fluid movement in various settings. This valve measures 3 inches and includes flat-faced flanged ANSI Class 125 connections for secure installation.

Weighing in at 82.0 lbs, it ensures durability through a die-formed carbon steel body that has a corrosion-resistant finish. For operational performance, the valve stroke is measured at 1-1/8 inches (29 mm), which is essential for effective control. It features brass trim that supports a modified linear flow profile, standardizing the fluid's movement through the valve.

The actuator is engineered to operate within a temperature scope of -29°C to 66°C, making it versatile for varying conditions. During storage, the actuator can tolerate temperatures as low as -40°C and as high as 80°C. The diaphragm is constructed from EPDM (Ethylene Propylene Diene Monomer), known for its durability against temperature fluctuations and exposure to fluids.

The unit's fluid operating range extends from 2°C to 138°C, allowing adaptability to different application requirements. In terms of pressure capabilities, the valve manages a closeoff pressure of 40 psig (276 kPa) with a spring range set between 9 to 13 psig (62 to 90 kPa). Its air connection employs a barbed fitting designed for 1/4-inch O.D. polytubing, enriching compatibility with various pneumatic systems.
