Parker Hannifin 902929P OROA-5 Head Pressure Control Valve 7/8" ODF 210 PSI

The Parker Hannifin 902929P is an OROA-5 series nonadjustable head pressure control valve designed for refrigeration systems. This valve performs the critical function of limiting the flow of liquid refrigerant from the condenser while simultaneously regulating the flow of hot gas around the condenser to the receiver, ensuring optimal system performance in varying ambient conditions.

Key Features:

• 7/8" ODF (Flare) connections for easy installation in refrigeration lines
• 210 PSI pressure rating for reliable operation in demanding applications
• OROA (Open on Rise of Outlet) pressure design provides automatic regulation
• Diaphragm-controlled main orifice responds to outlet pressure changes
• Nonadjustable factory-calibrated settings ensure consistent performance
• Suitable for commercial refrigeration and HVAC applications

This head pressure control valve is essential for maintaining proper condenser pressure during low ambient temperature operation, preventing issues such as liquid floodback and ensuring efficient system operation year-round. The OROA-5 series is trusted by HVAC professionals for its reliability and durability in critical refrigeration applications.
