Description
The Schneider Electric (Barber Colman) VB-7223-0-4-11 is a heavy-duty two-way globe valve engineered for precise flow control in commercial and industrial HVAC hydronic systems. With a 2″ NPT connection and a 40 Cv flow coefficient, this valve delivers the capacity needed for medium-to-large air handling and hydronic heating and cooling applications.
Equal Percentage Flow Characteristic
The equal percentage flow characteristic provides a consistent, proportional relationship between valve stem travel and flow rate change. This makes the VB-7223-0-4-11 ideal for modulating control applications where stable, repeatable performance across a wide range of load conditions is critical — minimizing hunting and improving system efficiency.
Durable Bronze Body with Brass Trim
Constructed with a bronze body and brass trim, this globe valve offers excellent corrosion resistance and long service life in hydronic water systems. The robust construction stands up to the demands of commercial HVAC environments, reducing maintenance requirements and extending system uptime.
Stem Up Closed (Normally Closed) Fail Position
The stem-up-closed configuration means the valve defaults to the closed position when the actuator is de-energized or loses power, providing a safe fail-safe operation that protects system components and prevents unintended flow.
