Schneider Electric VK-7223-203-4-6 Pneumatic Globe Valve 3/4" NPT Normally Closed 8-13 PSI 7.5 Cv

The Schneider Electric VK-7223-203-4-6 is a 2-way normally closed pneumatic globe valve assembly with a 3/4" NPT threaded connection, bronze body, and brass trim. This pre-assembled valve features a 7.5 Cv flow capacity and operates with an 8 to 13 PSI (55 to 90 kPa) pneumatic actuator spring range, making it ideal for precise flow control in commercial HVAC applications.

Key Features:

• Designed for control of chilled water, hot water, or steam in HVAC systems
• 7.5 Cv flow coefficient for moderate flow capacity
• 8-13 PSI pneumatic actuator with spring return operation
• Normally closed configuration for fail-safe operation
• Bronze body construction with brass trim and stainless steel stem
• Spring-loaded TFE packing for reliable sealing
• NEMA Type 1 enclosure with -20°F to 220°F operating temperature range

The VB Series valve body is rated for 400 PSI at 20°F to 150°F, decreasing to 321 PSI at 281°F, meeting ANSI B16.15-1985 Class 250 standards. Compatible media includes hot or chilled water, steam up to 35 PSI, and glycol solutions up to 50% concentration. This factory-assembled valve and actuator combination is ready for installation and provides reliable, precise flow control for commercial building automation systems.
