Resideo by Honeywell VU53S2034 1/2" Sweat N.C. Fan Coil Valve 3.5 Cv

The Resideo by Honeywell VU53S2034 is a normally closed (N.C.) fan coil valve designed for hydronic heating and cooling applications. This straight-through body valve features 1/2" sweat connections for direct copper tube installation, providing reliable flow control in fan coil units and other HVAC systems.

Key Specifications:

• Flow coefficient (Cv): 3.5 for efficient water flow control
• Maximum differential pressure: 20 PSI
• Connection type: 1/2" sweat (copper tube)
• Valve type: Normally closed (N.C.) - closes when de-energized
• Body style: Straight-through design for easy piping installation
• Operating temperature range suitable for chilled and hot water systems

This valve is ideal for controlling water flow in fan coil units, unit heaters, and radiators. The normally closed configuration ensures the valve automatically closes during power failure, providing a fail-safe shutoff. The straight-through body design minimizes pressure drop and simplifies installation in tight spaces.
