Description
The Honeywell VU53N1026 is a two-way, normally closed fan coil valve engineered for reliable flow control in hydronic heating and cooling systems. With a 1″ NPT connection and a flow coefficient (Cv) of 8, this valve delivers precise water flow regulation for fan coil unit applications in commercial and light-industrial buildings.
Key Features
- Two-way, normally closed configuration ensures safe fail-safe operation — valve closes upon loss of power or signal
- Quick-opening flow characteristic for responsive system control
- 1″ NPT end connections for straightforward installation into standard piping
- Flow coefficient (Cv) of 8 for accurate hydronic system balancing
- 10 PSI maximum close-off pressure rating
- Compatible with chilled water and hot water systems, including fluids with up to 60% glycol concentration
Construction & Materials
- Brass body for durability and corrosion resistance in hydronic applications
- Brass stem for reliable actuation and long service life
- Brass seat for tight shutoff and extended wear performance
- Buna-N rubber plug/ball/disc for excellent sealing across a wide range of hydronic fluids
- EPDM rubber packing for superior resistance to glycol solutions and temperature cycling
Applications
- Fan coil units in commercial HVAC systems
- Chilled water cooling systems
- Hot water heating systems
- Hydronic systems utilizing glycol antifreeze solutions (up to 60% concentration)
- Two-pipe and four-pipe fan coil installations
