Bulletin 71.1:CS800 Note In order for the Underpressure Shutoff (UPSO) of any slam-shut to be triggered, the downstream pipe pressure must drop below the UPSO setpoint. In the case of a downstream line break, numerous factors can prevent the downstream pipe pressure from decreasing below the slam-shut UPSO setpoint.
PAGE 16
Bulletin 71.1:CS800 Non-Relieving “N” Type numbers with the “N” suffix, e.g., Type CS800IN, do not provide internal relief discharge through the diaphragm assembly. The CS800 Series regulators have outlet pressure ratings that are lower than their inlet pressure ratings.
