The Johnson Controls VG2231TM+94NGGC is a 2-way globe control valve designed for efficient regulation of fluid flow within a system. This model features a valve size of 2 1/2 inches and uses flat-faced flanged ANSI Class 125 connections, which simplifies installation and enhances reliability.
Weighing in at 50.0 lbs, this valve has a 2-way, push-down-to-close body configuration specifically designed to spring to a closed position with the valve stem oriented downwards. The valve achieves a stroke length of 3/4 inch (19 mm) and is constructed with brass trim, offering a modified linear flow characteristic that improves control in various applications.
This unit operates at a voltage rating of 24 VAC or 24 VDC, and it is equipped to handle input frequency rates of 50/60 Hz. The current requirements for operation include approximately 0.65 Amps while running and around 0.32 Amps when holding at 24 VAC, ensuring efficient power usage.
The VG2231TM+94NGGC meets an IP rating of NEMA 2 (IP54), providing a degree of resistance to dust and water contact, suitable for indoor installations. The operational temperature for the actuator ranges from -40°C to 55°C, while it can be stored in conditions from -65°C to 85°C without loss of functionality. The fluid temperature range for effective operation spans 2°C to 138°C. This valve is capable of maintaining a close-off pressure rated at 76 psig (524 kPa), reliable for various fluid control requirements.
