Sporlan 902912P Valve
The Sporlan 902912P, also identified as the OROA-5-100, is a high-performance head pressure control valve designed for rapid response in air-cooled condensers. Featuring 7/8" ODF solder connections and a factory-set 100 PSI opening point, this mechanical valve maintains stable system performance during low ambient conditions. By modulating the flow of hot gas to the receiver and restricting liquid flow from the condenser, it ensures sufficient pressure across the thermostatic expansion valve (TXV) to prevent evaporator starving. The OROA-5 series combines the functions of an ORI (Open on Rise of Inlet) and an ORD (Open on Rise of Differential) into a single integrated housing, reducing piping complexity and potential leak points. For contractors servicing commercial refrigeration systems, this unit provides precise refrigerant head pressure control and eliminates the need for complex electrical cycles or fan cycling controls in many applications.
Key Benefits for HVACR Technicians:- Integrated Logic: Combines holdback and bypass functions into a single 7/8" ODF valve body for a cleaner installation.
- Low Ambient Protection: Maintains the required 100# pressure differential to ensure proper liquid feed to the expansion device.
- Durable Construction: Built with high-grade copper and brass components to withstand extreme vibration and thermal cycling.
- Reduced Piping: Minimizes the number of brazed joints compared to using separate ORI and ORD valves.
- Precise Modulation: Provides a more stable liquid line pressure than traditional fan-cycling switches.
What is the primary function of the OROA-5-100?
It is designed to maintain a minimum head pressure in the receiver during low ambient temperatures, ensuring the system operates within its design envelope throughout the year.
Can the 100 PSI setting be adjusted in the field?
No, the Sporlan 902912P is a non-adjustable, factory-set valve. If a different pressure threshold is required, a different OROA series model should be selected.
Is this valve compatible with all synthetic oils?
The materials used in the OROA-5 are compatible with standard refrigerants and lubricants used in modern commercial HVACR systems, including POE and MO oils.
