Schneider Electric VK-7211-201-3-4 2-Way Normally Open Globe Valve Assembly 1/2" Union Angle 5.0 Cv

The Schneider Electric (Barber Colman) VK-7211-201-3-4 is a 2-way normally open globe valve assembly designed for precise fluid control in HVAC heating and cooling systems. This valve features a 1/2-inch union angle body configuration with bronze construction and brass trim for corrosion resistance and long-term reliability.

Key Features:

• 5.0 Cv flow coefficient with equal percentage flow characteristic for precise modulating control
• Integrated spring return pneumatic actuator with 3-7 PSI operating range
• Stem-up open (normally open) design ensures fail-safe operation during air supply loss
• Union angle body pattern for easy installation and maintenance in tight spaces
• Suitable for hot water, chilled water, or low-pressure steam applications up to 281°F
• High rangeability provides accurate control across a broad range of flow conditions
• ANSI Class IV leakage rating ensures tight shutoff for energy conservation

This valve assembly is ideal for two-position on/off control or proportional modulating control applications in commercial HVAC systems. The brass trim and soft seat design provide ultra-low leakage on shutoff, helping to reduce energy consumption and improve system efficiency.
