Solenoid valve AEVRA and AFA
AEVRA is a direct or servo operated solenoid valve for liquid, suction and hot gas lines with ammonia or fluorinated refrigerants.
AEVRAT is an assisted lift, servo operated solenoid valve for liquid, suction and hot gas lines with ammonia and fluorinated refrigerants. AEVRAT is specially designed to open – and stay open – at a pressure drop of 0 bar.
AEVRAT 10-15 and AEVRA 20-25 have spindle for manual operation.
（1）MOPD for media in gas form is approx. 1 bar greater
（2）The kv value is the water flow in m3 /h at a pressure drop across valve of 1 bar, p = 1000 kg/m³
The rated cooling capacity test conditions for the liquid line and suction line are: evaporating temperature te=-10°C, liquid temperature at valve inlet=25°C, valve pressure differential ΔP=0.15 bar. The rated cooling capacity test conditions for the discharge line are: condensing temperature tc=40°C, valve pressure differential ΔP=0.8 bar, discharge gas temperature=65°C, subcooling degree Δtsub=4K.
