KMC Controls VEZ-4202BMBN Valve

The KMC Controls VEZ-4202BMBN is a precision-engineered 1/2-inch 2-way control valve designed for demanding HVAC hydronic applications. This normally closed (N/C) assembly features a 2.5 Cv flow coefficient, making it ideal for managing fluid dynamics in terminal units such as fan coils and reheat coils. Operating on a 24V power supply, this 2-position electric valve utilizes a robust VM-8202 actuator to ensure reliable shut-off and consistent flow control. The chrome-plated brass ball and reinforced PTFE seats provide high cycle life and chemical resistance against standard glycol mixtures. With its compact footprint and NPT female connections, this valve assembly simplifies installation in tight mechanical spaces while maintaining a high close-off pressure rating. For technicians seeking a dependable replacement HVAC valve, the VEZ-4202BMBN delivers field-proven performance and straightforward zone valve troubleshooting through its simplified two-wire configuration.

• Optimized Flow Control: The 2.5 Cv rating is specifically tuned for balanced flow in low-tonnage hydronic systems.
• Durable Internal Trim: Features a chrome-plated brass ball to prevent scale buildup and ensure long-term operation.
• High Torque Actuation: The paired VM-8202 actuator provides the necessary force for 100% shut-off against system pressure.
• Contractor-Friendly Design: The 2-position, 24V operation integrates seamlessly with most building automation systems and thermostats.

Is this valve suitable for steam applications?
No, this unit is designed for hot or chilled water and glycol solutions up to 50% concentration. Do not use this model for steam service.

What is the default position if power is lost?
The VEZ-4202BMBN is a normally closed valve, meaning it will return to the closed position upon loss of power to prevent unintended heating or cooling.

Can the actuator be replaced without removing the valve body?
Yes, the actuator is designed for field replacement, allowing for maintenance without draining the entire hydronic loop.
