Schneider Electric VS-2253-821-9-5 1/2" Two-Way Ball Valve 4.7 Cv Proportional 24V Spring Return Actuator

The Schneider Electric (Barber Colman) VS-2253-821-9-5 is a compact 1/2-inch two-way ball valve assembly designed for precise proportional control in commercial HVAC systems. This valve combines a brass ball valve body with an integrated 24-volt spring return electric actuator for reliable modulating control of hot and cold water applications.

Key Features:

• 1/2-inch NPT threaded connections for easy installation in standard piping systems
• 4.7 Cv flow coefficient provides sufficient capacity for typical hydronic applications
• Proportional control actuator enables precise modulating operation (not just on/off)
• 24V spring return actuator automatically returns valve to fail-safe position on power loss
• Two-way ball valve design for straightforward flow control and tight shutoff
• Durable brass construction resists corrosion in water-based systems
• Compact integrated design saves installation space and simplifies wiring

This valve is ideal for zone control, mixing applications, and general hydronic system control where proportional modulation is required. The spring return feature ensures the valve returns to a safe position during power interruptions, making it suitable for critical HVAC control applications.
