Schneider Electric VK4-7213-301-4-5 Pneumatic Globe Valve Assembly 3/4" Normally Open with Positioner

The Schneider Electric (Barber Colman) VK4-7213-301-4-5 is a 3/4-inch two-way pneumatic globe valve assembly designed for precise modulating control in commercial HVAC applications. This normally open valve features a 5.5 Cv flow coefficient and operates with a 3-6 PSI spring return pneumatic actuator equipped with an integral positioner for enhanced control accuracy.

Key Features:

• 3/4-inch NPT threaded bronze body with brass trim construction
• Two-way normally open configuration (stem up open)
• 5.5 Cv flow coefficient for optimal flow control
• MK-4601 pneumatic actuator with 3-6 PSI spring range
• Integral positioner for precise proportional control
• Equal percentage flow characteristic
• Linear actuator with spring return failsafe operation
• NEMA 1 enclosure rating
• 1/8-inch NPT air supply connection

This valve assembly is engineered for controlling chilled water, hot water, or steam in HVAC systems. The VB-7213 series valve body is pre-assembled with the pneumatic actuator and positioner, providing a ready-to-install solution. The positioner enables accurate valve positioning in response to control signals, making it ideal for critical temperature control applications requiring precise modulation. The normally open design ensures fail-safe operation, with the valve returning to the open position upon loss of air pressure.
