Parker Hannifin 902903P OROA-5 Head Pressure Control Valve 5/8" ODF 210 PSI

The Parker Hannifin 902903P is an OROA-5 series head pressure control valve designed to maintain optimal refrigeration system performance during low ambient conditions. This non-adjustable valve features 5/8" ODF (Outside Diameter Flare) solder connections and is rated for 210 PSI operating pressure.

Key Features:

• Limits refrigerant flow from the condenser while regulating hot gas flow to maintain proper liquid line pressure
• Main orifice controlled by valve diaphragm that opens on rise of outlet pressure
• Factory tested for positive leak-free performance
• Design working pressure of 450 PSI provides substantial safety margin
• Includes integral strainer for system protection
• 5/8" x 5/8" x 5/8" ODF solder connections for professional installation

This valve performs dual functions by holding back liquid refrigerant from the condenser while simultaneously regulating hot gas around the condenser to the receiver. Ideal for air conditioning and refrigeration applications including residential units, commercial systems, walk-in coolers and freezers, and split systems with remote condensers. Part of Parker's Sporlan Division HVACR components line with over 80 years of industry-leading innovation.
