KMC Controls VEZ-4103AMBM 3/4" 2-Way Normally Open Zone Valve 4.1 Cv 24V Spring Return

The KMC Controls VEZ-4103AMBM is a 3/4-inch two-way zone valve designed for precise control in HVAC hydronic systems. This normally open (NO) valve features a 4.1 Cv flow coefficient, making it suitable for medium-flow applications in commercial and industrial building automation systems.

Key Features:

• 3/4-inch NPT threaded connections for standard piping integration
• Two-way valve configuration for on/off or modulating control
• 4.1 Cv flow coefficient for efficient water flow management
• Normally open design - valve closes when power is applied
• 24V AC/DC spring return actuator for fail-safe operation
• Spring return mechanism ensures valve returns to open position on power loss
• Compatible with KMC building automation and DDC control systems
• Brass construction for durability and corrosion resistance

This valve is ideal for zone control applications including heating and cooling coils, fan coil units, radiant heating systems, and other hydronic distribution applications where reliable on/off or modulating control is required. The spring return feature provides fail-safe operation, automatically returning the valve to the open position during power failures to prevent system freeze-ups or overheating.
