Schneider Electric VK-7211-201-3-8 1" Normally Open Union Angle Valve 16cv 3-7 PSI

The Schneider Electric (Barber Colman) VK-7211-201-3-8 is a 2-way normally open union angle valve assembly designed for precise control of water and steam in commercial HVAC systems. This 1-inch valve features a 16 cv (flow coefficient) rating with equal percentage flow characteristics, making it ideal for proportional control applications.

Key Features:

• 1-inch union angle connection for flexible installation
• 16 cv flow coefficient for mid-range flow capacity
• Normally open (N/O) configuration - valve closes when actuator is energized
• 3-7 PSI spring return pneumatic actuator included
• Bronze body with brass trim construction for durability and corrosion resistance
• Equal percentage flow characteristics for precise temperature control
• Operates with water from 20°F to 281°F (-7°C to 138°C) or steam up to 281°F (138°C)
• Suitable for two-position or proportional control applications

This valve assembly is part of the VB-7211 series and comes complete with the MK-2690 pneumatic actuator and AV-7400 linkage. The normally open design ensures fail-safe operation, allowing flow when air pressure is lost. Ideal for heating, cooling, and steam control in commercial building automation systems.

Note: Actuator and valve linkage are included with this assembly.
