Schneider Electric VK4-7213-201-4-5 3/4" Pneumatic Globe Valve Assembly Normally Open with Positioner

The Schneider Electric (Barber Colman) VK4-7213-201-4-5 is a two-way normally open globe valve assembly featuring an integrated pneumatic actuator with positioner for precise proportional control in commercial HVAC applications. This factory-assembled valve combines a 3/4-inch NPT threaded bronze body valve with a 3-7 PSI spring return pneumatic actuator, providing reliable control of chilled water, hot water, or steam.

Key Features:

• 3/4-inch NPT threaded connections for easy installation
• 5.5 CV flow coefficient for efficient fluid control
• Normally open configuration with spring return fail-safe operation
• 3-7 PSI pneumatic actuator with integrated positioner for accurate proportional control
• Bronze body construction with brass trim for durability and corrosion resistance
• Two-position or proportional control capability
• ANSI Class IV leakage rating (0.01% of CV)
• Suitable for water temperatures from 20°F to 281°F (-7°C to 138°C) or steam up to 281°F

Part of Schneider Electric's VB-7000 Series valve family, this assembly is designed specifically for HVAC control applications including heating and cooling systems. The VK4 prefix indicates this unit includes a factory-installed positioner, enabling precise analog control signals for modulating applications. The equal percentage flow characteristic provides excellent control across a wide range of operating conditions.
