The Johnson Controls VG2831VM+845E01 is engineered as a 3-way mixing flanged globe valve that operates through pneumatic actuation. This component is constructed to withstand a body rating conforming to ASME B16.1, Class 125 standards, ensuring adequate pressure handling. The valve has dimensions of 4 inches and features a weight of 151.0 lbs. It effectively controls fluid flows across a temperature spectrum ranging from 2°C to 138°C, catering to a variety of operational scenarios.

The actuator associated with this valve has robust storage capabilities, rated to handle temperatures as low as -40°C and as high as 80°C. Its exterior is fabricated from die-formed carbon steel and finished in black, offering solid protection against corrosion. With a flow coefficient rated at Cv 131 and Kv 112.3, this valve provides efficient operation while maintaining system integrity.

Designed with a stroke length of 1 1/8 inches (29 mm), it is fitted with brass trim that contributes to its modified linear flow characteristic. The VG2831VM+845E01 connects easily via Class 125 ANSI flat-faced flanged connections for seamless integration into existing systems. The combination of these features establishes it as a reliable component within fluid regulation and mixing applications.
