KMC Controls VEZ-4302BMBB 1/2" 2-Way Zone Control Valve 2.5 Cv Proportional 0-10VDC 24V Fail-in-Place

The KMC Controls VEZ-4302BMBB is a globe zone control valve designed to regulate the flow of hot or chilled water in HVAC applications such as VAV terminal unit reheat coils, fan coil units, and induction units. This 1/2" NPT two-way valve features a 2.5 Cv flow coefficient and operates with proportional 0-10VDC control signal at 24V power supply.

Key Features:

• Compact design allows easy installation within small enclosures
• Normally open valve body construction
• Proportional 0-10VDC control for precise modulation
• Fail-in-place actuator with position indication and manual override
• Tool-free replacement actuator installation
• Non-spring return actuator with visual position indication
• Manual override capability (requires 3mm hex wrench)
• CE compliant and UL listed

The VEZ-4302BMBB features a non-fail-safe actuator design where the valve remains in its last position upon power loss, making it ideal for applications requiring fail-in-place operation. The 2.5 Cv rating provides efficient flow control for medium-capacity HVAC zones, while the proportional control input ensures accurate temperature regulation and energy efficiency.
