KMC Controls VCZ-4102AMBD Valve (2 left On Clearance Sales)

The KMC Controls VCZ-4102AMBD is a high-performance 1/2 inch 2-way pneumatic zone control valve engineered for precision in commercial HVAC systems. This normally open (N/O) assembly features a 1.0 Cv flow coefficient and is driven by a 3-8 psi spring range actuator. Designed for modulating or on/off control of hot and chilled water, it is a standard choice for VAV terminal unit reheat coils, fan coil units, and finned tube convectors. The VCZ-4102AMBD valve utilizes a rugged, glass-filled nylon actuator housing and a durable neoprene diaphragm to ensure consistent seating and long-term reliability under varying line pressures up to 125 PSI.

For service technicians and mechanical contractors, this KMC pneumatic valve offers significant field advantages, including a tool-free actuator replacement mechanism. The compact envelope is ideal for tight mechanical enclosures and retrofit applications where spacing is a premium. With a temperature limit ranging from 40??F to 180??F, the KMC Controls VCZ series maintains linear flow characteristics for stable environmental control. This specific clearance sale unit provides an exact OEM replacement for maintaining legacy pneumatic infrastructure.

• Precise Flow Regulation: Optimized 1.0 Cv rating provides accurate throttling for terminal heating and cooling equipment.
• Fail-Safe Operation: The normally open configuration ensures full flow upon loss of pilot air, protecting coils from freezing.
• Rapid Maintenance: Field-replaceable actuator can be removed and installed without specialized tools or system drainage.
• Broad Compatibility: Standard 1/2" FNPT connections and a 3-8# spring range integrate seamlessly with existing pneumatic control systems.

What is the maximum operating pressure for the VCZ-4102AMBD?
This valve is rated for a maximum inlet pressure of 125 PSI and is designed for water applications with up to 50% glycol concentrations.

Can I use this valve for steam applications?
The KMC VCZ-4102AMBD is specifically rated for hot and chilled water within a 40??F to 180??F range; it is not intended for high-pressure steam service.

How do I verify if the 3-8 psi range is correct for my controller?
The 3-8 psi actuator spring range is standard for many proportional thermostats. If your controller outputs a 0-20 psi signal, ensure the start point and span match your sequence of operations for proper modulation.
