Schneider Electric VK4-7213-301-4-8 Pneumatic Globe Valve Assembly 1 Inch NPT 14 Cv with Positioner

The Schneider Electric (Barber Colman) VK4-7213-301-4-8 is a 2-way normally open globe valve assembly designed for precise control of chilled water, hot water, or steam in HVAC applications. This factory-assembled unit combines a bronze body globe valve with a pneumatic spring return actuator and integral positioner for enhanced control accuracy.

Key Features:

• 1 inch NPT threaded connection for easy installation
• Flow coefficient (Cv) of 14.0 for efficient fluid control
• Normally open (N/O) configuration with spring return operation
• 3-6 PSI spring range for reliable actuation
• Integral positioner provides precise valve positioning and proportional control
• Bronze body construction with brass trim and soft seats
• Equal percentage flow characteristic for accurate modulation
• Suitable for water temperatures from 20°F to 281°F (-7°C to 138°C)
• Compatible with steam applications up to 281°F (138°C)

The VK4 series valve assemblies are part of Schneider Electric's VB Series globe valves, which have a long-standing reputation for quality and reliability in building automation systems. The integral positioner enhances control precision by ensuring accurate valve positioning throughout the full stroke range, making this assembly ideal for proportional control applications in heating and cooling systems.
