Parker Hannifin 902926P OROA-5 Head Pressure Control Valve 7/8" ODF 180 PSI

The Parker Hannifin 902926P is an OROA-5 series head pressure control valve designed for refrigeration and air conditioning systems. This nonadjustable valve performs dual functions by limiting liquid refrigerant flow from the condenser while simultaneously regulating hot gas flow around the condenser to the receiver, ensuring optimal system performance in varying ambient conditions.

Key Features:

• 7/8" ODF (Flare) connections on all three ports for easy installation
• 180 PSI pressure rating for reliable operation
• Nonadjustable design provides consistent, maintenance-free performance
• Maintains proper head pressure during low ambient temperature conditions
• Prevents condenser flooding and ensures adequate refrigerant flow to expansion device

This valve is essential for maintaining stable head pressure in refrigeration systems, particularly in applications where outdoor ambient temperatures fluctuate significantly. The OROA-5 series is widely used in commercial refrigeration, walk-in coolers, and air conditioning installations where consistent system performance is critical.
