EVAPORATOR PRESSURE REGULATING VALVES(S)ORIT-12, -15 and -20 Features
- High side pilot for improved temperature control and low ?P operation
- Optional solenoid Ã¬stopÃ® feature to close valve during defrost
- Normally open design allows system evacuation without manual operator
These EPRs are pilot operated using Ã¬high sideÃ® pressure and require a pilot supply connection from the compressor discharge to operate. They are designed to be Ã¬normally openÃ® providing an unparalleled ability to operate with virtually no suction line pressure drop. The pilot operated design does not require the Ã¬allowable evaporator pressure changeÃ® necessary with the direct acting models, and can be simply sized based on design evaporator temperature and available pressure drop across the valve at full load conditions.
