Schneider Electric VK-7213-201-4-8 Pneumatic Valve Actuator 1" NPT 3-7 PSI

The Schneider Electric (Barber Colman) VK-7213-201-4-8 is a pneumatic valve actuator designed for HVAC control applications. This spring return actuator provides reliable on/off control for compatible valves in heating, cooling, and process control systems.

Key Specifications:

• Connection: 1" NPT (National Pipe Thread)
• Action: Normally Open (N/O) - valve is open when de-energized
• Operating Pressure Range: 3-7 PSI (pounds per square inch)
• Flow Coefficient (Cv): 14
• Spring Return Design: Automatically returns to fail-safe position on air pressure loss

This actuator is engineered for commercial and industrial building automation systems where pneumatic control is required. The normally open configuration ensures the valve opens upon loss of control signal, making it suitable for safety-critical applications. The 3-7 PSI operating range is compatible with standard pneumatic control systems.
