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

Capacities are bad on liquid temperature t l = +25°C ahead of valve, evaporating temperature t e
= -10°C, and superheat 0 K.
Correction factors
When sizing valves, the plant capacity must be multiplied by a correction factor depending on liquid temperature t l ahead of valve/evaporator.When the corrected capacity is known, the lection can be made from the table.
