Data sheet
Solenoid valves type EVRA 3 ® 40
Introduction
EVRA is a direct or servo operated solenoid valve for liquid, suction and hot gas lines with ammonia or fluorinated refrigerants.
EVRA valves are supplied complete or as
separate components, i.e. valve body, coil and flanges can be ordered separately.

1)
Valve body with gaskets, bolts and 10 W a.c. coil. Please specify code no., voltage and frequency. Voltage and frequency can also be given in the form of an appendix number, see table "Appendix numbers", under EVR.
Rated hot gas capacity is based on condensing tempera-ture t c = +40°C,
pressure drop across valve D p = 0.8 bar,hot gas temperature t h = +65°C,
and subcooling of refrigerant D t sub = 4 K.
