The Johnson Controls VG2831VM292NGGA is constructed as a 3-way flanged globe mixing valve, tailored to accommodate various hydraulic systems. Designed with a robust cast iron body coated in black lacquer, it ensures durability and longevity. The valve measures 4 inches, making it suitable for substantial flow requirements. It is notable for its weight of 126 lbs, indicating a solid construction necessary for performance under demanding conditions.
At the heart of its functionality, the VG2831VM292NGGA incorporates a spring return mechanism. It allows the valve to operate with a stem-up orientation while keeping the side inlet port closed when used alongside Tandem M9220 actuators. The valve employs Class 125 ANSI flat-faced flanged connections at its ends, promoting reliable integration into piping systems.
The valve's trim consists of brass material with a modified linear flow characteristic, which aids in controlling the flow dynamics efficiently. Operating temperatures for the fluid can vary from 2°C to a high of 138°C, reflecting its versatility for different applications. Additionally, the actuator can withstand a storage temperature range from -40°C to 55°C, ensuring operational capability under varied environmental conditions.
In terms of pressure handling, the closeoff pressure is rated at 22 psig, providing reliable sealing during operation. The VG2831VM292NGGA is rated for use at 24 VAC/DC with a frequency of 50/60 Hz, and its actuators consume 15.5 VA while running and 7.7 VA in holding mode, ensuring efficient energy usage during operation. This valve is a strong choice for applications needing reliable mixing and control of fluids effectively.
