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
