Sporlan 902903P Valve
The Sporlan 902903P Valve, specifically the OROA-5 head pressure control, is a non-adjustable solution designed to maintain system stability in air-cooled condensers during low ambient conditions. This 5/8" ODF connection valve functions on the principle of backing up liquid refrigerant into the condenser to reduce its effective surface area. By modulating flow between the condenser and the receiver while simultaneously bypassing hot gas, the OROA-5 210# control ensures that the receiver pressure remains at the necessary 210 PSI setpoint. This operation is critical to prevent low suction pressure and evaporator icing, which can lead to compressor failure. Built with a forged brass body and featuring a metal-to-metal knife edge joint, this low ambient head pressure control is engineered for high-pressure refrigeration and air conditioning systems with a maximum rated pressure of 450 psig. For optimal performance, ensure all HVACR piping is sized correctly—typically matching the condenser outlet—to maintain proper velocity and oil return within the circuit.
Key Benefits
- Maintains 210 PSI receiver pressure to ensure consistent thermostatic expansion valve (TEV) performance during cold weather startups and operation.
- Integrated hot gas bypass functionality eliminates the need for a separate tee in the liquid drain line, streamlining the HVAC unit installation.
- Hermetic brass construction provides a durable, leak-proof solution for demanding commercial and industrial refrigerant flow control.
- Optimized for low ambient stability, preventing system short-cycling and protecting the compressor from damage caused by low head pressure.
Common Questions
Can the OROA-5 210# be adjusted in the field?
No, the Sporlan OROA-5 is a non-adjustable valve. The 210# designation indicates a factory-set pressure. If your application requires different parameters, you must select the valve with the specific required setpoint (e.g., 100# or 180#).
Where should this valve be installed in the system?
The OROA-5 must be installed in the liquid line. It should never be placed in the discharge line, as compressor pulsations can significantly degrade the internal components and lead to premature valve failure.
Does this valve include an inlet strainer?
This specific model is the "less strainer" version. While the Sporlan 902903P does not include a built-in strainer, installing an external 40-mesh strainer is highly recommended to protect the metal-to-metal seat from system debris.
