Description
Overview
The Schneider Electric (Barber Colman) VK-7213-201-4-3 is a complete valve and actuator assembly engineered for precise flow control in commercial HVAC and building automation systems. This factory-matched assembly pairs a 2-way normally open globe valve with a spring return pneumatic actuator, delivering reliable, repeatable performance in hydronic heating and cooling applications.
Valve Features
- Configuration: 2-way, normally open (NO)
- Connection: 1/2″ NPT threaded
- Flow coefficient: 2.2 Cv
- Flow characteristic: equal percentage for accurate, proportional flow control
- Body material: bronze for corrosion resistance and long service life
- Trim material: brass for durability and compatibility with hydronic media
- Valve style: globe valve for tight shutoff and precise modulation
Pneumatic Actuator Features
- Actuator type: spring return pneumatic
- Control signal range: 3–7 PSI
- Spring return action ensures fail-safe normally open position on loss of air pressure
- Designed for use with pneumatic control systems in commercial buildings
Applications
- Hydronic heating and cooling coil control
- Fan coil unit (FCU) and air handling unit (AHU) valve control
- Commercial building automation and pneumatic control systems
- Zone flow control in two-pipe and four-pipe HVAC systems
Why Choose the VK-7213-201-4-3
As a factory-assembled and matched valve-actuator combination, the VK-7213-201-4-3 eliminates compatibility guesswork and simplifies installation. The equal percentage flow characteristic provides superior control at partial load conditions — the most common operating state in commercial HVAC — while the bronze body and brass trim ensure long-term reliability in demanding hydronic environments. The 3–7 PSI spring return actuator integrates seamlessly with standard pneumatic control systems.
