| Leadership: The Trane Air Valve 
The Trane air valve is designed to offer total comfort. Total comfort means not only a comfortable environment for building
occupants, but also a quiet, efficient product that is
rugged and reliable for the system designer and installer.
Quiet And Efficient
1 A
computer designed, carefully tested inlet with integral
flow diffuser and bevelled, self-centering damper. The
contoured diffuser and bevelled damper have been geometrically optimized to
give Venturi-like performance. This yields:
- Low inlet static pressure requirements.
- Quieter operation across the full operating range.
- Smooth, evenly distributed airflow regardless of valve position.
2 The Trane
patented multipoint flow ring and linear airflow
characteristics combine to provide accurate airflow
sensing and stable zone control, regardless of inlet ductwork configurations.
3 Low leakage is
possible without the need of gasketing or neoprene
seals that wear over time. Bevelled, self-centering
damper and precision cast aluminum inlet provide a
mechanical seal with less than one percent leakage
at four inches static pressure.
Rugged And Reliable
4 An integral
electric or pneumatic actuator means no linkages,
screws, pins, levers or rods to loosen, get out of
adjustment or be exposed to jobsite abuse.
5 High
reliability through the use of proven technology and
fewer parts. Balanced thrust of airflow and actuator
results in very low bearing forces. A simple yet reliable electric drive incorporates integral motor gear.
6 Rugged
construction. The VariTrane air valve can withstand 20
inches of inlet static pressure!
7 Consistent
quality. Aluminum die casting allows consistency in
every unit. Critical manufacturing tolerances are engineered into the casting design and do not rely on factory adjustments for
proper alignment and assembly.
