Resideo VC7934ZZ31 Modulating Zone Valve 0-10VDC 24V 120 Second

The Resideo by Honeywell VC7934ZZ31 is a modulating zone valve designed for precise hydronic heating and cooling system control. This valve features 0-10VDC modulating control for proportional flow regulation, providing superior temperature control compared to traditional on/off valves.

Key Features:

• 0-10VDC modulating control input for proportional flow control
• 24VAC power supply requirement
• 120-second actuator timing for smooth, controlled valve positioning
• 3-wire cable connection for simplified installation
• Ideal for radiant heating, fan coil units, and multi-zone HVAC applications
• Compatible with modern DDC and building automation systems

The modulating design allows the valve to open and close proportionally based on the control signal, enabling precise temperature management and improved energy efficiency. The 120-second timing ensures gradual transitions that reduce system stress and water hammer.
