Schneider Electric VK-7211-203-4-9 Normally Open Union Angle Valve Assembly 1-1/4" 8-13 PSI

The Schneider Electric (Barber Colman) VK-7211-203-4-9 is a 1-1/4" 2-way union angle valve assembly designed for precise control of water and steam in HVAC applications. This normally open (N/O) valve assembly features a stem-up-open design with an integrated spring return pneumatic actuator for reliable two-position or proportional control.

Key Features:

• 1-1/4" union angle connection for easy installation and maintenance
• 8-13 PSI spring range pneumatic actuator with spring return operation
• Normally open (stem up open) configuration for fail-safe operation
• Bronze body construction with brass trim for durability and corrosion resistance
• Equal percentage flow characteristic for accurate control
• Controls water from 20°F to 281°F (-7°C to 138°C) or steam up to 281°F (138°C)
• NEMA 1 enclosure rating for standard indoor applications
• Compatible with two-position on/off or proportional control strategies

This valve assembly is part of the proven VB-7211 series and is ideal for controlling chilled water, hot water, or low-pressure steam in commercial HVAC systems. The union angle design allows for compact installation in tight spaces while providing easy access for service. The 8-13 PSI spring range provides reliable actuation and positive shutoff when air pressure is removed, making it suitable for critical control applications requiring fail-safe normally open operation.
