Catalog CIC-2003-1/US
Suction Capacities A8, (S)PORT and SC
Capacities are based on 100°F liquid, 10°F superheat at valve inlet, and are maximum for the conditions listed. For each 10°F liquid is below 100°F,
INCREASE capacity values by 4%. (*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 3 psi should be used in the regulator selection process. If a pressure drop of more
than 3 psi 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 3 psi pressure drop, and should not be considered for these types of systems.
