General

NRF(E), RT(E) is dedicated to R410A series thermal expansion valve is an integrated expansion valve, suitable for air conditioning, commercial refrigeration, transportation, air conditioning and refrigeration and other fields.

Superheat regulation

The factory setting of static superheat is 4K, and the adjustable range is 1K-8K. Adjustment method: Unscrew the bottom sealing nut, turn the adjusting rod one turn clockwise (close the small), increase the static superheat by 1.5K, turn the adjustment rod one turn counterclockwise (open large) and decrease the static superheat by 1.5K.

Pressure balance type: After the model, the letter “E” is in the form of external balance, and the letter “E” is not in the form of internal balance.

Other Technical Data

The nominal cooling capacity is based on the following operating parameters: condensing temperature: Tc=38°C; evaporating temperature: Te=4°C; entering the valve liquid refrigerant: TL=37°C; subcooling degree: Tsub=1k; factory static superheat setting :ss=4K;
