The Johnson Controls VG2231VM294NGGC is engineered as a 2-way normally-closed flanged globe valve ideal for precise control in heating and cooling systems. It has a size of 4 inches, making it suitable for a range of applications. This valve features a stem type characterized by a 3/8-inch threaded configuration, commonly referred to as an 'M' stem.
The actuation mechanism is managed by the M9220-GGC-3 electric actuator, which is designed for spring return. This actuator is mounted tandemly, meaning it comes with two factory-installed actuators to enhance its performance. The control signal operates in a proportional range from 0 VDC to 10 VDC, allowing for smooth modulation of flow. Operating on a supply voltage of 24 VAC, it ensures compatibility with typical control systems.
The VG2231VM294NGGC has a closeoff pressure capability of 37 psig, making it robust for demanding applications. The valve stroke measures 1 1/8 inches for effective operation. Additionally, it features end connections compatible with Class 125 ANSI flat-faced flanges, providing secure attachment to piping systems. Constructed from cast iron and finished with black lacquer, the body ensures durability and reliability in service applications.
The stem is made of 316 stainless steel, known for its corrosion resistance, ensuring longevity even in varying fluid conditions. This valve operates efficiently over a fluid temperature range from 2°C to 138°C, enhancing its versatility for different media types in various environmental settings.
