Schneider Electric VK4-7213-201-4-6 3/4" Pneumatic Globe Valve Assembly with Positioner

The Schneider Electric (Barber Colman) VK4-7213-201-4-6 is a complete pneumatic globe valve assembly designed for precise fluid control in HVAC and building automation systems. This pre-assembled unit combines a bronze globe valve body with an integrated pneumatic actuator and positive positioner for accurate proportional control.

Key Features:

• 3/4 inch NPT threaded connection for straightforward installation
• Two-way normally open (N/O) configuration with stem-up-to-close action
• 7.5 Cv flow coefficient for efficient fluid handling
• Bronze body construction with brass trim and soft seats
• Pneumatic actuator with 3-7 PSIG spring return (also compatible with 5-10 PSIG and 8-13 PSIG ranges)
• Integrated positive positioner (AK-42309-500) for precise proportional control
• 60 PSI close-off pressure rating
• 1/8 inch FNPT air connections for supply line
• NEMA 1 protection rating

This valve assembly is suitable for controlling hot or chilled water, steam up to 35 PSIG, and glycol solutions up to 50% concentration. The media temperature range is 20° to 281°F (-7° to 138°C). The bronze body meets ANSI B16.15-1985 Class 250 specifications with a pressure rating of 400 PSI at ambient temperatures. The stainless steel stem and spring-loaded TFE packing ensure reliable, leak-free operation with ANSI Class IV leakage rating.

The included positive positioner enables two-position on/off control or proportional analog control, making this valve assembly ideal for variable flow applications in commercial HVAC systems, industrial process control, and building automation installations.
