KMC Controls VEZ-4104AMBM 1" Electric Ball Valve 2-Way Normally Open 24V

The KMC Controls VEZ-4104AMBM is a 1-inch electric ball valve designed for precise control in commercial HVAC and building automation systems. This 2-way valve features a normally open (NO) configuration with 24-volt spring return actuator, providing reliable fail-safe operation during power loss.

Key Specifications:

• Port size: 1 inch (25mm) threaded connection
• Flow coefficient (Cv): 7.0 for optimized flow capacity
• Actuator: 24V AC/DC spring return mechanism
• Configuration: 2-way normally open (fails open on power loss)
• End connections: NPT threaded female ports
• Body material: Brass construction for durability and corrosion resistance
• Ball and stem: Stainless steel components

Features and Benefits:

• Spring return actuator ensures valve returns to open position during power failure for safety
• 7.0 Cv rating provides excellent flow capacity for 1-inch applications
• Compatible with KMC building automation systems and BACnet controllers
• Compact design for easy installation in tight spaces
• Low power consumption for energy efficiency
• Suitable for hydronic heating, chilled water, and hot water systems

This valve is ideal for zone control, fan coil units, unit heaters, and other HVAC applications requiring reliable on/off or modulating control. The normally open design makes it particularly suitable for applications where flow is required during power outages.
