KMC Controls VEZ-4102BMBM Valve

The KMC Controls VEZ-4102BMBM is a professional-grade 1/2-inch 2-way globe zone control valve designed specifically for regulating hot or chilled water in demanding HVACR environments. This normally open (NO) valve features a high-performance 2.5 Cv flow coefficient, making it ideal for terminal unit applications such as VAV reheat coils, fan coil units, and induction systems. Engineered for precision, the integrated 24V spring return actuator ensures a reliable fail-safe position during power loss, maintaining system safety and efficiency. The compact bronze body construction allows for seamless installation in tight mechanical enclosures, while the NPT threaded connections provide a secure, leak-proof fit for standard piping. Contractors appreciate the tool-free actuator mounting, which simplifies field servicing and reduces downtime. With its ability to handle high inlet pressures and varied fluid temperatures, this KMC zone valve is a staple for building automation professionals looking for long-term consistency in hydronic flow control and energy management.

• Fail-Safe Reliability: The 24VAC spring return mechanism ensures the valve reverts to a normally open state, preventing coil freeze-ups or overheating during power interruptions.
• Precise Flow Regulation: A 2.5 Cv rating provides the accurate throttling necessary for stable temperature control in VAV and fan coil applications.
• Contractor-Friendly Design: The compact footprint and 1/2" NPT connections facilitate fast installs in restricted areas, while replacement actuators click into place without specialized tools.
• Modern Compatibility: Fully compatible with standard 24-volt HVAC controllers and building automation systems for seamless integration into existing hydronic loops.

What is the maximum operating pressure for the KMC VEZ-4102BMBM?
This globe valve is typically rated for a maximum inlet pressure of up to 125 PSI, making it suitable for most commercial low-to-medium pressure hydronic systems.

Can the actuator be replaced without removing the valve body?
Yes, the KMC Controls design allows the actuator to be swapped out without breaking the pipe seal, significantly lowering maintenance labor costs.

Does this valve support glycol-based fluids?
The internal trim and seals are designed to handle both hot and chilled water, as well as typical water/glycol mixtures used in closed-loop heating and cooling systems.
