Flo-Con Pressure
Regulators
& Valves
Capacities are based on 40°C liquid, 5°C superheat at valve inlet, and are maximum for the conditions listed. For each 5°C liquid is below 40°C,
INCREASE capacity values by 7%. (*Sizing charts are also for Crankcase Pressure Regulators in sizes to 2 1/8 port only.)
NOTE: Due to conditions encountered with refrigeration circuits utilizing hot gas for defrosting purposes, a
maximum pressure drop of .20 bar should be used in the regulator selection process. If a pressure drop of more
than .20 bar is considered, the regulator could become restrictive after the termination of a defrost cycle, thereby
requiring an extended pull down period. The shaded areas of the suction tables designate regulator capacities
above a .20 bar pressure drop, and should not be considered for these types of systems.
