KMC Controls VCZ-4102BMBE 1/2" Normally Open 2-Way Zone Valve

The KMC Controls VCZ-4102BMBE is a 1/2-inch normally open (N/O) 2-way zone valve designed for precise control in HVAC hydronic systems. This actuated valve features a 2.5 Cv flow coefficient and operates with spring return functionality in the 8-13 PSI range, making it ideal for chilled water, hot water, and glycol solution applications.

Key Features:

• 1/2-inch threaded NPT connection for standard piping integration
• Normally open configuration provides fail-safe operation during power loss
• 2-way design for on/off flow control in zone applications
• 2.5 Cv rating delivers adequate flow capacity for small to medium zones
• Spring return actuator with 8-13 PSI operating range
• Bronze or brass body construction for durability and corrosion resistance
• Suitable for heating and cooling system applications

This zone valve is commonly used in commercial and residential HVAC systems for controlling water flow to individual zones, fan coil units, and terminal equipment. The normally open design ensures flow continues if power is lost, which is critical for freeze protection in heating applications.
