Solenoid valves for R 410A and R744 (CO2)
EVR 2 to EVR 8 and EVRH 10 to EVRH 40

EVR 2 and EVR 3 (direct operated) and EVR 4 to
EVR 8 / EVRH 10 to EVRH 40 (servo-operated) are
high pressure solenoid valves specially designed
to meet the requirements of high pressure
refrigerants such as R410A and R744 (CO2).
The EVRH valve can be used for liquid, suction
and hot gas lines.

The table values refer to evaporator capacity
and are given as a function of evaporating
temperature te and pressure drop ∆p across the
valve. Capacities are based on liquid temperature
tl = 100 °F ahead of the expansion valve and
superheat ts = 7 °F. For each additional 10 °F of
superheat, the table capacities must be reduced
by 2%.

Correction factors for liquid temperature t

l

When liquid temperature tl ahead of the
expansion valve is other than 100°F, adjust
the table capacities by multiplying them by
the appropriate correction factor found in the
following table:

tl˚F 80 90 100 110 120
Factor 1.10 1.05 1.00 0.95 0.90
