Solenoid Valves
The Refrigerating Specialties family of solenoid
valves includes direct operated and pilot operated
valves. Selections for most refrigeration applica-
tions are available – liquid, suction, hot gas and
compressor unloading. Low or no pressure
differential, equalizing and vent solenoid in sizes
up to 50mm (2").
Explosion proof SV2X and S4X hazardous
environment type solenoids carry NEMA Type 4
and 7 classification.
Coils are stocked in standard voltages. Non-
standard voltages may be special ordered. See
table on page 394 or consult factory.
