KMC Controls VCZ-4103AMBE 3/4" NPT 2-Way Normally Open Control Valve

The KMC Controls VCZ-4103AMBE is a 3/4-inch NPT threaded 2-way normally open control valve designed for precise flow control in HVAC and building automation systems. This spring-return actuated valve features a 4.1 Cv rating for reliable fluid flow capacity and operates on 8-13 PSI control pressure.

Key Features:

• 3/4-inch NPT threaded connections for standard pipe fitting compatibility
• 2-way normally open configuration - valve closes when pressure is applied
• 4.1 Cv rating provides adequate flow capacity for hydronic systems
• 8-13 PSI operating pressure range for pneumatic control integration
• Spring-return actuator ensures fail-safe open position during power loss
• Suitable for hot water, chilled water, and glycol solution applications

This valve is ideal for zone control, fan coil units, unit heaters, and other HVAC applications requiring modulating or on/off control. The normally open design provides system flow when no control signal is present, making it an excellent choice for safety-critical heating applications.
