The Johnson Controls VG2231TL+823E01 is a robust 2-way pneumatically-actuated globe control valve ideal for managing fluid and gas controls. Weighing 49 lbs, this valve features flat-faced flanged ANSI Class 125 connections, making integration straightforward in various systems. Its design incorporates a body configuration that utilizes a push-down-to-close mechanism along with an "L" stem variant measuring 3/8 inches.

The valve size of 2 ½ inches permits significant flow while maintaining control. With a stroke of 3/4 inches (19 mm) and brass trim for modified linear flow, this unit is tailored for responsive and precise operation in dynamic environments. It supports a maximum control and supply air pressure of 25 psig (172 kPa) and a closeoff pressure of 28 psig (193 kPa), ensuring reliable performance in firm control applications.

The actuator operates effectively across a temperature range of -29°C to 66°C, while its diaphragm is made from EPDM material, ensuring durability and resilience against various environmental factors. In terms of storage, it withstands temperatures from -40°C to 80°C. Designed for fluid operation temperatures between 2°C and 138°C, this valve is appropriate for diverse applications.

An air connection is facilitated via a barbed fitting compatible with 1/4-inch O.D. polytubing. The carbon steel housing with a corrosion-resistant finish enhances the life expectancy of the valve, making it suitable for long-term operations in demanding settings.
