Manufactured by Johnson Controls, the VG2231UM+94NGGA is a 2-way electrically-actuated globe control valve that provides efficient control of fluid flow in various settings. This valve features a size of 3 inches, equipped with flat-faced flanged ANSI Class 125 connections which simplify installation within piping systems.
The valve's unique body configuration operates as a push-down-to-close mechanism and is designed to spring closed, offering reliability and safety in operation. It employs brass trim for modified linear flow characteristics which assist in achieving accurate flow management.
The VG2231UM+94NGGA valve functions with a proportional control signal in the range of 0-10 Volts DC, with selectable options for 0-20 mA and 4-20 mA through the use of a field resistor. Its voltage rating is set at 24 VAC, functioning seamlessly within AC input voltage frequencies of 50/60 Hz, while delivering a current rating of approximately 0.65 Amps during operation and about 0.32 Amps on hold.
With an NEMA 2 (IP54) ingress protection rating, the valve is safeguarded against dust and moisture, making it durable for various environments. The actuator operates efficiently in temperatures as low as -40°C and up to 55°C. For storage, it can withstand temperatures ranging between -65°C and 85°C. The fluid operating temperature of the valve ranges from 2°C to 138°C, supporting multiple fluid types.
This valve features a closeoff pressure capability of 33 psig (228 kPa), ensuring effective sealing during operation. The combination of features makes the VG2231UM+94NGGA an excellent choice for various control applications, delivering reliability and precision in flow management.
