Schneider Electric VK4-7213-201-4-7 1 Inch NPT Pneumatic Globe Valve Assembly with Positioner

The Schneider Electric (Barber Colman) VK4-7213-201-4-7 is a professional-grade two-way pneumatic globe valve assembly designed for precise fluid control in HVAC systems. This 1 inch NPT threaded valve features a normally open (N/O) configuration with a spring return actuator and integrated positive positioner for enhanced control accuracy.

Key Features:

• 1 inch NPT threaded connection for easy installation
• 10 Cv flow coefficient for efficient fluid handling
• 3-7 PSI spring return pneumatic actuator provides reliable fail-safe operation
• Integrated positive positioner (AK-42309-500) ensures accurate valve positioning
• Two-way normally open design allows flow when air pressure is lost
• Bronze body with brass trim construction for durability and corrosion resistance
• Straightway body pattern for minimal pressure drop
• MK-2690 actuator with AV-7400 linkage for smooth operation

This valve assembly is ideal for controlling hot water, chilled water, or steam in commercial and industrial HVAC applications including fan coil units, air handlers, and terminal reheat coils. The positive positioner provides proportional control capability, allowing for precise modulation in response to control signals. The VB Series from Schneider Electric is known for its high quality and reliability in building automation systems.
