Parker 902926P Valve

Maintain consistent system performance with the Parker 902926P, a specialized OROA-5 head pressure control valve designed for mission-critical low ambient operation. As a non-adjustable condenser flooding valve, the OROA-5 effectively manages refrigerant flow by restricting liquid discharge from the condenser while simultaneously diverting hot gas to the receiver. This dual-action refrigerant regulator ensures that the liquid line maintains the necessary pressure to prevent TXV hunting and evaporator icing when outdoor temperatures drop. Built with a rugged brass body and 7/8" ODF copper sweat connections, this 180 PSI factory-set valve is engineered for durability in commercial refrigeration and industrial HVACR environments. The integrated steel diaphragm provides precision response to outlet pressure changes, eliminating the need for complex manual adjustments. By stabilizing the high-side pressure, this Sporlan head pressure control prevents insufficient refrigerant feed and maintains the thermal expansion valve's capacity, protecting the compressor from the cycling issues common in unmanaged systems.

Key Benefits:

• Consistent Head Pressure: Automatically maintains 180# head pressure to ensure stable liquid feed to the expansion device during cold weather.
• 7/8" ODF Connections: Standardized copper-to-copper solder ports facilitate a secure, leak-free installation into existing discharge and liquid lines.
• No-Adjust Design: Factory-calibrated OROA-5 series eliminates field errors, providing reliable setpoints without the risk of manual tampering.
• Condenser Flooding Logic: Optimizes system efficiency by utilizing the condenser surface area to regulate pressure through refrigerant backup.
• Industrial Build Quality: Features high-grade brass construction and a 40-mesh insertable strainer to protect internal components from system debris.

Common Questions:

How does the Parker 902926P prevent evaporator icing?
When ambient temperatures drop, head pressure naturally falls, which can starve the evaporator. This valve maintains high-side pressure at 180 PSI, ensuring the thermostatic expansion valve (TXV) receives enough liquid refrigerant to keep the evaporator coil from reaching freezing temperatures.

Can this valve be field-adjusted if I need a different setpoint?
No, the OROA-5 is a non-adjustable valve. It is factory-set to a specific pressure (180 PSI in this model) to provide "set it and forget it" reliability for contractors and facility managers.

Where should the OROA-5 be located in the piping circuit?
Standard practice places the valve between the condenser outlet and the receiver inlet. It must be piped so it can bypass hot gas directly to the receiver while simultaneously throttling the liquid leaving the condenser.
