Johnson Controls presents the VG2231UM+92NGGA, a specialized 2-way electrically-actuated globe control valve. Weighing in at 64 lbs, this valve is designed with a size of 3 inches to fit seamlessly into system designs. It offers robust flat-faced flanged ANSI Class 125 connections for secure installations. The body is structured for a push-down-to-close operation, employing a spring-to-open system featuring a valve stem positioned upwards.
In terms of performance, this valve includes brass trim that allows for modified linear flow, enhancing fluid dynamics within the system. The unit operates on a control signal type proportional to the input voltage, which can be set to either 0-10 Volts DC or configured using selectable options of 0-20 mA or 4-20 mA through an appropriate field resistor. It functions at a voltage rating of 24 VAC with an input frequency of 50/60 Hz.
Current ratings for the valve are approximately 0.65 Amps during operation at 15.5 VA and roughly 0.32 Amps while holding at 7.7 VA, both at the 24 VAC rating. This valve meets the NEMA 2 (IP54) rating, providing a decent level of protection against dust and moisture.
The actuator is built to perform effectively across a temperature range from -40°C to 55°C during operation and can be stored in environments ranging from -65°C to 85°C. In terms of the fluid it handles, the valve accommodates temperatures varying from 2°C to 138°C. The valve supports a closeoff pressure of 33 psig (228 kPa), indicating its suitability for standard pressure applications. This valve is engineered for those seeking reliable performance in HVAC and industrial control systems.
