Schneider Electric VK4-7213-201-4-3 1/2" Pneumatic Globe Valve 2.2CV Normally Open with Positioner

The Schneider Electric (Barber Colman) VK4-7213-201-4-3 is a two-way pneumatic globe valve assembly designed for precise control of hot water, chilled water, or compatible fluids in HVAC systems. This 1/2-inch NPT threaded valve features a normally open configuration, ensuring flow continuity in the event of control signal loss.

Key Features:

• Flow coefficient (Cv) of 2.2 for optimal fluid flow control
• 3-6 PSI spring range pneumatic actuator with integrated positioner
• Durable bronze body construction with brass trim for corrosion resistance
• Normally open (N.O.) design provides fail-safe operation
• Integrated positioner enables precise modulating control
• 1/2-inch NPT threaded connections for easy installation

This valve assembly is ideal for use in fan coil units, air handlers, terminal reheat applications, and other HVAC control systems requiring accurate modulating control. The included positioner allows for precise positioning feedback and enhanced control accuracy, making it suitable for demanding climate control applications where maintaining optimal temperatures and energy efficiency is critical.
