Electrical Coil Information
Class “ B” Coil
The molded water resistant Class “B” solenoid coil, avail-
able on most Refrigerating Specialties solenoid valves, is
designed for long life and powerful opening force. The
standard coil housing meets NEMA 3R and 4 requirements.
This sealed construction can withstand direct contact with
moisture and ice. The coil housing far exceeds the require-
ments of NEMA Standard ICS.1-110.57 salt spray test for
rust resistance.
By definition, Class “B” coil construction will permit coil
temperatures, as measured by resistance method, as high
as 130°C (266° F). Final coil temperatures are a function of
both fluid and ambient temperatures. The higher fluid
temperatures require lower ambient temperatures so the
maximum coil temperature is not exceeded. Conversely,
low fluid temperatures permit higher ambient temperatures.
The supply circuits must be properly sized to give adequate
voltage at the coil even when other electrical equipment is
operating. The coil is designed to operate with line voltage
from 85% to 110% of rated coil voltage. Power consump-
tion during normal operation will be 33 watts or less.
Standard Encapsulated Coils
For other voltages, contact factory. On transformer coil, the 6 volt
leads are always black.
Class “ H” Coil (SV2 only)
The Refrigerating Specialties Division molded water
resistant Class “H” coil is designed for long life and powerful
opening force. The Class “H” coil construction will permit
coil temperatures, as measured by resistance method, as
high as 180°C (365° F).
The supply circuits must be properly sized to give adequate
voltage at the coil leads even when other electrical equip-
ment is operating. The coil is designed to operate at 15%
under voltage. Operating with line voltage below the limit
will result in lowering the valve opening pressure differen-
tial.

Coils are available from stock with most standard voltages
(see table below). Non-standard voltages (shown in shaded
area of table) can be special ordered. Coils are also
available with 6V secondary voltage for use with remote
pilot lights PLT-1 and PLT-2.
