Description
Schneider Electric (Barber Colman) VB-8223-0-5-12 Two-Way Globe Valve Overview
The Schneider Electric (Barber Colman) VB-8223-0-5-12 is a heavy-duty, two-way globe valve engineered for precise flow control in commercial and industrial HVAC hydronic systems. Featuring a 2-1/2″ flanged connection, this valve delivers a high flow capacity of 56 Cv with an equal percentage flow characteristic — ideal for applications requiring accurate modulating control across a wide range of system loads. The ANSI Class 125 cast iron body provides robust durability for demanding hydronic and steam service environments, while the brass trim ensures reliable, corrosion-resistant performance at the seat and stem.

Application & Benefits
The equal percentage flow characteristic of the VB-8223-0-5-12 makes it particularly well-suited for modulating control in heating and cooling coil applications, where precise temperature regulation is critical. As flow increases, the valve provides a proportional percentage increase in flow rate, delivering stable and responsive control across the full stroke range. The stem-up-closed (normally closed) configuration ensures the valve defaults to a closed position upon actuator de-energization, providing a safe fail-safe operation.
Compatibility
Designed to be paired with Schneider Electric (Barber Colman) compatible actuators for automated modulating or on/off control. The flanged end connections conform to ANSI Class 125 standards, simplifying integration into existing piping systems. Suitable for use in chilled water, hot water, and low-pressure steam hydronic systems.
