Description
This heavy duty solenoid valve is suitable for ammonia and
other common refrigerants, certain oils and other fluids
approved for use in refrigeration. The S7 is a pilot operated,
positive lift valve. The valve may be opened by means of a
manual opening stem for servicing or in case of electrical
power failure.
It is advisable to install a strainer upstream of each valve to
prevent entrance of foreign material into the valves and the
rest of the system. Refrigerating Specialties strainers are
available to close-couple to valve inlets (see page 436).
