Description
This compact, heavy duty, pilot-operated solenoid valve is
suitable for ammonia and other common refrigerants,
certain oils and other fluids approved for use in refrigera-
tion. This valve may be opened by means of a manual
opening stem for servicing or in case of electrical power
failure. The valve can be ordered with a close-coupled
stainless steel screen strainer (see page 436).
The Type SV2 valve is available with an optional extension
tube to raise the solenoid operator and coil housing
assembly 50mm (2") above the valve body to accommodate
insulation. When the option is desired, the Type SV2A
solenoid valve should be specified.
