Schneider Electric VK-7213-201-4-5 3/4" NPT Pneumatic Globe Valve 3-7 PSI 5.5 Cv

The Schneider Electric (Barber Colman) VK-7213-201-4-5 is a two-way, normally open pneumatic globe valve designed for controlling water from 20 to 281°F or steam to 281°F maximum in commercial HVAC heating and air conditioning systems. This valve assembly features a 3/4" NPT threaded connection, making it compatible with standard piping systems.

Key Specifications:

• Connection Size: 3/4" NPT threaded
• Flow Coefficient (Cv): 5.5
• Spring Return Pressure Range: 3-7 PSI
• Valve Configuration: Normally Open (N/O), stem up open
• Body Material: Bronze with brass trim
• Flow Characteristic: Equal percentage
• Maximum Operating Temperature: Water 20-281°F (-7 to 138°C), Steam 281°F (138°C)

Features & Applications:

• Pre-assembled valve and pneumatic actuator for convenient installation
• Suitable for two-position or proportional control applications
• Bronze construction provides excellent corrosion resistance and durability
• Spring return pneumatic actuator ensures reliable operation and fail-safe positioning
• Ideal for hot water, chilled water, and steam control in fan coil units, air handlers, and hydronic heating systems

This valve assembly is part of Schneider Electric's VB-7213 series, known for high quality and reliability in commercial HVAC applications. The normally open configuration means the valve allows full flow when no air pressure is applied to the actuator, and closes as pressure increases within the 3-7 PSI control range.
