Schneider Electric VK-7211-201-3-5 2-Way Globe Valve Union Angle Normally Open 3/4" 5.5 Cv

The Schneider Electric (Barber Colman) VK-7211-201-3-5 is a 2-way normally open globe valve assembly designed for precision control of hot water, chilled water, or low-pressure steam in HVAC applications. This valve features a 3/4-inch union angle body pattern with NPT connection and delivers a flow coefficient of 5.5 Cv for efficient flow control in heating and air conditioning systems.

Key Features:

• Bronze body construction with brass trim for durability and corrosion resistance
• Stem-up open (normally open) design provides fail-safe operation
• Integrated MK-2690 pneumatic actuator with spring return mechanism
• 3-7 PSI spring range for 2-position (On/Off) or proportional control
• Temperature range: 20°F to 281°F (-7°C to 138°C) for water and steam applications
• Equal percentage flow characteristic for precise modulation
• NEMA 1 enclosure rating for standard indoor applications
• Linear mechanical movement for smooth, reliable operation

Part of the proven VB-7211 series, this valve assembly is engineered for demanding HVAC control applications where reliability and precision are essential. The union angle connection simplifies installation and maintenance, while the pneumatic actuator provides responsive control for both two-position and proportional control strategies. The normally open configuration ensures that flow continues in the event of air pressure loss, making it ideal for safety-critical heating applications.
