Product Features

  • Balanced‑port design stabilizes performance under wide evaporator‑load and ambient‑condition shifts
  • Bi‑flow structure supports both cooling and heating modes for heat‑pump systems with one single valve
  • Standard external equalizer compensates pressure loss across long or multi‑pass evaporators
  • Corrosion‑resistant stainless‑steel power element lowers failure risk and extends service lifespan
  • Hermetic leak‑proof joint construction to prevent refrigerant leakage
  • Compact form factor, fits confined equipment cabinet spaces
  • Multiple capacity and tube‑connection variants for flexible system matching
  • Factory‑calibrated superheat setting ready for field installation

Applicable scenarios

  1. Residential & light‑commercial R‑410A heat‑pump units: Installed inside packaged heat‑pump systems to meter refrigerant for both heating and cooling cycles.
  2. Small commercial air‑conditioning units: For split‑system AC equipment using R‑410A, stabilizes evaporator superheat under fluctuating cooling loads.
  3. Retrofit / HVAC repair replacement: Used by service technicians to replace failed original expansion valves in existing R‑410A refrigeration‑air‑con units.
  4. Custom‑built compact refrigeration equipment: OEM integration for small capacity process cooling systems running R‑410A refrigerant.
  5. Multi‑circuit evaporator air handlers: External‑equalizer capability addresses pressure drop inside long‑run evaporator coil circuits.
