REFRIGERATION & AIR CONDITIONING Parker Pressure Regulators

Head Pressure Controls • 3-way non-adjustable head pressure control valve • Limits the flow of refrigerant from the condenser to the receiver • Maintains more consistent head pressure than fan cycling controls • Install in liquid line between condenser and receiver • LAC-4 capacity: 2.25 nominal ton capacity for R404a at 2 PSI pressure drop, 0°F evaporator, 110°F condenser and 10°F subcooling

• LAC-5 capacity: 5.39 nominal ton capacity for R404a at 2 PSI pressure drop, 0°F evaporator, 110°F condenser and 10°F subcooling • OROA-5 capacity: 9.15 nominal ton capacity for R404a at 2 PSI pressure drop, 0° evaporator, 110°F condenser and 10°F subcooling • Use 100 PSI for R134a, 180 PSI for R22 and 210 PSI for R404a Warning: Cancer and Reproductive Harm - www.P65Warnings.ca.gov
