KMC Controls VCZ-4104AMBD 1" Two-Way Pneumatic Zone Control Valve Assembly

The KMC Controls VCZ-4104AMBD is a 1-inch two-way pneumatic globe zone control valve assembly designed to regulate the flow of hot or chilled water in commercial HVAC applications. This normally open (NO) valve features a 7.0 Cv flow coefficient and operates with a 3-8 PSI pneumatic actuator, configured to fail open for added safety.

Key Features:

• 1-inch NPT threaded connections for easy installation
• Two-way normally open valve configuration
• 7.0 Cv flow coefficient for optimal water flow control
• 3-8 PSI pneumatic actuator with fail-open safety feature
• Rugged glass-filled nylon actuator housing with neoprene diaphragm
• Compact design ideal for installation in small enclosures
• Tool-free actuator replacement for simplified maintenance
• Maximum inlet pressure rating of 125 PSIG

This valve assembly is ideal for controlling water flow in VAV terminal unit reheat coils, fan coil units, induction units, finned tube convectors, and cast iron radiators. The precision pneumatic actuator ensures reliable operation, while the compact footprint allows for installation in space-constrained applications. The actuator can be field-replaced without tools, minimizing downtime during maintenance.
