Description
These heavy duty, normally closed, gas powered valves are
suitable for control of ammonia and other common refriger-
ants, certain oils and other fluids approved for use in
refrigeration.
The Type S9 are pilot operated but use an external source
of higher pressure gas to operate the valve and, therefore,
require no minimum pressure drop to open. The external
gas pressure must be at least 0.71 bar (10 psi) above valve
internal upstream pressure for positive opening.
The S9 valve can be ordered without a pilot assembly and
the pilot assembly ordered separately (see page 392).
