Schneider Electric VK-7213-201-4-9 Pneumatic Control Valve 1-1/4" NPT

The Schneider Electric (Barber Colman) VK-7213-201-4-9 is a pneumatic control valve designed for commercial HVAC applications requiring precise fluid flow control. This normally open (N/O) valve features a 1-1/4" NPT threaded connection and operates on a 3-7 PSI pneumatic signal range, making it ideal for use with pneumatic actuators and control systems.

Key Specifications:

• Valve coefficient (Cv): 20, providing high flow capacity for medium to large systems
• Connection size: 1-1/4" NPT female threaded ports
• Actuator signal range: 3-7 PSI pneumatic
• Fail-safe position: Normally open (N/O) - valve opens on loss of air pressure
• Construction: Bronze body with stainless steel trim for durability and corrosion resistance
• Temperature range suitable for standard HVAC applications

This valve is commonly used in hot water, chilled water, and glycol solution systems where reliable flow control is essential. The normally open design provides fail-safe operation by allowing flow when control air pressure is lost, making it suitable for heating applications where continued flow is desired during system failures. The 20 Cv rating delivers excellent flow characteristics for systems requiring substantial flow capacity.
