Schneider Electric VK4-7213-611-4-11 2-Inch Pneumatic Globe Valve Assembly with Positioner

The Schneider Electric VK4-7213-611-4-11 is a factory-assembled 2-inch two-way globe valve with integrated pneumatic actuator and positive positioner, designed for precise proportional control in commercial HVAC applications. This assembly combines a VB-7213 series brass trim globe valve with an MK-6601 pneumatic actuator and AK-42309-500 positive positioner for enhanced control accuracy.

Valve Specifications:

• 2-inch NPT threaded connection
• Two-way configuration with stem up open (normally open)
• Brass trim with soft seats for tight shutoff
• 40 Cv flow coefficient for high-capacity applications
• Maximum pressure rating of 250 PSI (up to 400 PSI below 150°F)
• Designed for chilled water, hot water, and steam control

Actuator and Control Features:

• Pneumatic spring return actuator with 3-8 PSI control range
• Normally open (N/O) fail-safe operation
• Integrated positive positioner (AK-42309-500) for accurate valve positioning
• Suitable for proportional or two-position control applications
• 1/8-inch NPT air connections

The VB-7200 series valves feature a patented precision plug design that provides high rangeability and efficient heat transfer across a broad range of HVAC applications. The Venta seal design ensures tight close-off for energy efficiency while maintaining reliable performance at differential pressures up to 87 PSI. This pre-assembled unit arrives ready for installation, eliminating field assembly requirements.
