KMC Controls VEZ-4204AMBN 1" 24V Normally Closed Electric Valve

The KMC Controls VEZ-4204AMBN is a 1-inch two-way electric control valve designed for precision fluid control in HVAC and building automation systems. This 24-volt actuated valve features a normally closed (N/C) configuration with spring return (S/R) functionality, ensuring fail-safe operation that automatically closes when power is removed.

Key Specifications:

• Port Size: 1 inch NPT threaded connections
• Valve Type: 2-way (two-position control)
• Flow Coefficient (Cv): 7.0 for accurate flow capacity calculations
• Voltage: 24VAC/DC actuator operation
• Configuration: Normally Closed (N/C) - closed when de-energized
• Actuator Type: Spring return (S/R) for fail-safe positioning
• Construction: Bronze body with stainless steel trim

This valve is ideal for hydronic heating and cooling systems, chilled water applications, and general HVAC zone control where reliable on/off control is required. The spring return mechanism provides automatic failsafe closure during power failures or emergency shutdowns, making it suitable for critical control applications in commercial and industrial building automation systems.
