Description
The Schneider Electric (Barber Colman) VB-7213-0-4-2 is a precision-engineered two-way globe valve designed for hydronic heating, cooling, and HVAC control applications. Built with a durable bronze body and brass trim, this valve delivers reliable, long-service performance in commercial and industrial building automation systems.
Key Features
- Two-way, equal percentage flow characteristic for precise, stable flow modulation across the full stroke range
- 1/2″ NPT connections for straightforward installation into standard piping systems
- 1.3 Cv flow coefficient — optimized for low-to-medium flow hydronic and HVAC applications
- Bronze body construction for excellent corrosion resistance and long service life
- Brass trim components for durability and compatibility with water and glycol solutions
- Stem Up Open (SU/O) fail-safe action — valve opens when actuator power or signal is lost
- Designed for use with compatible Schneider Electric / Barber Colman actuators

The equal percentage flow characteristic makes the VB-7213-0-4-2 ideal for applications requiring fine, proportional control at low flow rates while still providing full capacity at higher demands — a critical advantage in variable-flow hydronic systems. The stem-up-open configuration ensures the valve defaults to an open position upon loss of actuator signal, providing a built-in fail-safe for heating or cooling continuity.
