Description
Schneider Electric (Barber Colman) VB-7211-0-4-2 Two-Way Globe Valve
The Schneider Electric (Barber Colman) VB-7211-0-4-2 is a precision-engineered two-way globe valve designed for reliable flow control in commercial HVAC hydronic systems. Featuring an equal percentage flow characteristic, this valve delivers accurate and proportional modulation across its full stroke — making it an ideal choice for heating and cooling coil applications where precise temperature control is critical.
Constructed with a durable bronze body and brass trim, the VB-7211-0-4-2 is built to withstand the demands of commercial building automation and hydronic piping systems. The 1/2″ NPT x union end connections simplify installation and future servicing, while the stem-up-open (normally closed) fail-safe position ensures system safety in the event of actuator power loss.

Why Choose the VB-7211-0-4-2?
As part of the trusted Schneider Electric (Barber Colman) valve family, the VB-7211-0-4-2 is engineered for compatibility with a wide range of Schneider Electric actuators. The union end connections allow the valve body to be removed from the piping without disturbing the actuator, reducing maintenance downtime. The equal percentage flow characteristic ensures smooth, stable control across varying system loads — a key advantage in variable-flow hydronic systems.
