(S)ORIT-PI-2, -3, -4 and -5 Features
Piloted internally (No high side connection required)
Superior corrosion resistance
Optional solenoid “stop” feature to close valve during defrost
Optional electric open feature for “two temperature operation”
Manual lift stem (standard) to allow system evacuation

These EPRs are Piloted Internally using the natural pressure drop across the valve to operate and do not require a “high side” pilot connection. And, like the (S)ORIT valves, the pilot operated design does not require the “allowable evaporator pressure change” 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.

Design improvements to the SORIT-PI family of valves has resulted in removable ports so that components can now be exchanged to increase or decrease valve capacity. This unique feature allows the valve to become adaptable for application updates or refrigerant conversions.
