TRAE Thermal Expansion Valves

TRAE Thermal Expansion Valves

New TRAE thermal expansion valve stretches down to 8 to 18 tons and is ideal for application requiring compact size combined with stable and accurate control over wide evaporating temperature ranges.

TRAE Stretch series of Thermal Expansion Valves are designed predominantly for AC, heat pumps, close control, industrial process cooling applications, and transportation AC with HP demand.

The new TRAE stretches down to 8-18 Ton range and introduces a very compact design, consequently it is ideal for those applications requiring hermetic/compact size combined with stable and accurate control over wide load and evaporating temperature ranges.

Key features:

• Hermetic valve with brazing connections
• Compact size design
• Compatible with R410A / R407C / R22
• Maximum working pressure: 46.9 bar
• Bi-Flow application
  • Balanced port in normal and reverse flow directions eliminates disturbance forces resulting from condensing pressure
  • Optimum static superheat in normal and reverse flow
  • Capacities performance in normal and reverse flow correlates to capacity of heat pumps in cooling and heating mode
• Desired reverse superheat setting is much suitable for Heat Pump application in heating model.
• Stainless steel power element with special diaphragms design provides life expectancy against high pressure during reversed flow via external equalizer.
• Special factory setting upon request
