Super HF thermostatic expansion valves feature a balanced port construction which provides stable and accurate superheat control over a wide range of operating conditions.

  • External superheat adjustment
  • Replaceable power element for added flexibility
  • Bi-flow capability up to 5 1/2 tons R22 allows one valve to control the superheat in both cooling and heating modes for package unit heat pump applications
  • Balanced port construction compensates for changes in operating pressures due to varying ambients, gas defrost, heat reclaim, or widely varying evaporator loads
  • Optional, removable, 100 mesh strainer allows cleaning without removing valve from line
  • Overall height: 4 1/32"
  • Connection: 3/8" ODF 90° inlet x 1/2" ODF outlet
