common commercial refrigerants along with certain
oils. The SC solenoid may be opened by means of a
manual opening stem for servicing or in case of an
electrical power failure.
The SC-II series of valves are manufactured with com-
pletely corrosion resistant materials including aluminum
bronze bodies and cartridge assemblies, and stainless
steel adapter bolts. Cartridges, and solenoids are inter-
changeable with the (S)PORT-II regulator line.
Variations: SC1/ SC-II Solenoids: Five port sizes, from
3/8" (9mm) through 1-3/8" (35mm). SC2 Solenoid: three
port sizes, from 1-5/8" (42mm) through 2-5/8" (66mm).
Installation: SC 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.
When brazing in line, typically a wet cloth wrapped
around the valve body is recommended to dissipate
heat. If a valve is disassembled prior to installation,
always have the correct gasket/ O-ring kit available
for reassembly. The internal cartridge-to-body O-ring
will need to be replaced prior to reassembly.
Electrical: SC commercial solenoid valves utilize a
molded water resistant Class “F” solenoid coil with an
open frame coil housing that meets NEMA 3R and 4
requirements. A class “H” DIN coil is also available with
certain voltages. Power consumption during normal
operation will be 10.2 watts or less.
All coils except for the 208/240V/60Hz version operate
with a 300 psi (20.7 bar) maximum opening pressure
differential (MOPD). The 208/240V/60Hz coil operates
with a 280 psi (19.3 bar) MOPD.
All 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 (SC1, SC-II or
SC2), port and connection size, coil voltage, and
frequency.
