Description
The Parker-Sporlan 902903P OROA-5 is a refrigeration evaporator pressure regulator (EPR) designed to maintain a minimum evaporator pressure in commercial and industrial refrigeration systems. Operating on an open-on-rise-of-outlet-pressure principle, this automatic-reset valve prevents the evaporator from operating below a set pressure, protecting against coil freeze-up and ensuring consistent system performance.
Key Features
- Model OROA-5 evaporator pressure regulator (EPR) from Parker-Sporlan
- 5/8″ ODF sweat connections for straightforward field installation
- 210 PSI maximum operating pressure rating
- Open-on-rise-of-outlet-pressure design maintains minimum evaporator pressure
- Automatic reset operation — no manual intervention required after pressure normalization
- Compact, rugged construction suited for commercial and industrial refrigeration applications
- Compatible with a wide range of common refrigerants
Application
The OROA-5 is ideal for use in multi-temperature refrigeration systems, walk-in coolers, display cases, and other applications where maintaining a consistent minimum evaporator pressure is critical. By preventing excessive pressure drop across the evaporator, this valve helps protect compressors, maintain product temperatures, and optimize overall system efficiency.
