Key Product Features

  • Optimized internal element calibrated specifically for R22 and R407C refrigerants
  • Stable superheat regulation across varying evaporator load conditions
  • Built‑in internal equalization for reliable evaporator performance
  • Compact HVAC‑R form factor for field replacement and OEM assembly
  • Robust thermostatic power element for long‑term cyclic operation
  • Multiple capacity variants (2‑8 nominal tonnage range) within one product family
  • Designed for direct‑expansion evaporator circuits in cooling equipment

Specific Use‑Case Scenarios

  1. Residential / commercial split air‑conditioning retrofits: Used when replacing a failed original expansion valve on R22 or R407C direct‑split cooling systems during maintenance jobs.
  2. Medium‑temperature walk‑in coolers: Installed within walk‑in cooler refrigeration loops that run R22 or R407C to control evaporator refrigerant feed.
  3. Packaged rooftop HVAC unit servicing: Field technicians select AAE series valves for repairing older packaged rooftop cooling systems using these legacy refrigerants.
  4. HVAC equipment rebuild workshops: Assemblers fit these valves during rebuild of remanufactured air‑cooled condensing units working with R22 / R407C refrigerants.
