Schneider Electric (Barber Colman) VB-7313-0-4-10 Valve

The Schneider Electric VB-7313-0-4-10 is a high-performance 3-way mixing globe valve designed for precision control of water or glycol solutions in demanding HVAC applications. This 1 1/2 inch NPT valve features a rugged bronze body and brass trim, ensuring reliable service life in hydronic systems. With a 28 Cv flow coefficient, it provides the necessary capacity for medium-to-high flow terminal units and heat exchangers. This model utilizes a proportional control linear stroke, making it compatible with a wide range of Schneider Electric valve actuators. The stem-up-to-close configuration (Port A to AB) allows for seamless integration into existing Barber Colman or Drayton legacy installations. Built for flow mixing duty, this valve ensures stable temperature regulation by accurately modulating the ratio of hot and cold return water. Its threaded NPT connection and robust packing assembly make it a standard choice for contractors looking for HVAC replacement valves that maintain system pressure integrity up to 250 psi.

• High Flow Capacity: Features a 28 Cv rating to handle significant volumetric flow rates without excessive pressure drop.
• Durable Construction: The bronze body with brass trim offers superior corrosion resistance compared to standard iron valves.
• Universal Compatibility: Direct replacement for many legacy Barber Colman valve bodies, simplifying field retrofits.
• Precise Modulation: Engineered for mixing applications, providing linear flow characteristics for stable loop control.

Common Questions Regarding the VB-7313-0-4-10

Can this valve be used for diverting applications?
No, the VB-7313-0-4-10 is specifically designed as a 3-way mixing valve. Using a mixing valve for diverting service can cause premature seat wear and hydraulic noise due to the internal flow dynamics.

What actuators are compatible with this 1 1/2 inch globe valve?
This valve is compatible with Schneider Electric Forta, Mx41 series, and legacy Barber Colman pneumatic or electronic actuators using the appropriate linkage kits.

What is the maximum fluid temperature for this valve body?
The VB-7313 series is typically rated for saturated steam up to 15 psi or chilled and hot water applications ranging from 20°F to 281°F, depending on the specific packing used.
