Johnson Controls offers the VG2231UM+845C01, a 2-way pneumatically-actuated globe control valve. This valve is designed for efficient fluid regulation and features a valve size measuring 3 inches. Constructed with flat-faced flanged ANSI Class 125 connections, this unit weighs 82.0 lbs.

The body of the valve is configured as a push-down-to-close type, providing straightforward operation. It has brass trim that allows for modified linear flow characteristics, ensuring precise control over the flow rates. The valve stroke is recorded at 1-1/8 inches (29 mm), enabling effective modulation during operation.

For actuator functionality, the spring range is set between 3 to 7 psig or 21 to 48 kPa, ensuring reliable performance across varying pressure conditions. The air connection is facilitated via a barbed fitting compatible with 1/4-inch O.D. polytubing, simplifying installation and setup.

Housed within a die-formed carbon steel body, the control valve comes with a corrosion-resistant finish, enhancing its durability in demanding environments. Operating temperatures for the actuator range from -29°C to 66°C, while it can be stored safely between -40°C and 80°C. The diaphragm material is EPDM (Ethylene Propylene Diene Monomer), delivering resilience in challenging operating conditions. The fluid operating temperature range is from 2°C to 138°C, making this valve suitable for a variety of applications. Closeoff pressure is rated at 75 psig (517 kPa), ensuring effective sealing capabilities during operation.
