Installation: S8 solenoid valves can be mounted either
in a vertical or horizontal line with the refrigerant flow in
the direction of the arrow on the body. These valves
may be soldered into the line without disassembly. A
wet cloth should be wrapped around the valve and the
soldering flame should be directed away from the valve
body.
If a valve is disassembled prior to installation, always
have the correct gasket/O-ring kit available for reas-
sembly. The internal cartridge-to-body O-ring will need
to be replaced prior to reassembly
Electrical: S8 commercial solenoid valves utilize a
molded water resistant Class “H” solenoid coil with a
general purpose coil housing which meets NEMA 3R
and 4 requirements. A class “H” DIN coil is also avail-
able with certain voltages. Power consumption during
normal operation will be 10.2 watts or less. The coils
are designed to operate with a line voltage from 85% to
110% of rated coil voltage. Operating with a line voltage
above or below these limits may result in coil burn out.
Ordering Guide: Specify valve type (S81 or S82), port
and connection size, and coil voltage and frequency.
Technical Information S81/S82 Solenoid Valves
Description: The S8 series of commercial solenoids
was developed as a versatile, general purpose, com-
mercial refrigeration valve, capable of being applied in
most liquid, hot gas, or suction applications. With
cartridge (port) sizes available up to 2-5/8" (66mm) in
size, S8 solenoids offer the greatest capacity of any
non-flanged commercial solenoid in the industry. The
unique design of the S8 solenoid is a mirror image of
the A8 regulator line, utilizing the same cartridges,
solenoid coil assemblies, bodies, and internal parts as
those used in the construction of the A8’s. With this
flexible line of commercial solenoids complementing
the complete line of commercial A8 regulators, a wide
offering of high capacity commercial refrigeration
control valves are now available from a single source.
Similar to the A8 regulators, S8 solenoids are manufac-
tured with ductile iron bodies with brazed copper cou-
plings, and are suitable for most common commercial
refrigerants along with certain oils. The S8 solenoid
may be opened by means of a manual opening stem
for servicing or in case of an electrical power failure.
Variations: S81 Solenoid: Five port sizes, from 3/8"
(9mm) through 1-3/8". S82 Solenoid: Three port sizes,
from 1-5/8" through 2-5/8".
NOTE: For S81 / S82 valve suction capacity tables, please reference pages 290-297 of this catalog.
