WARNING
The Type 92B safety override system
does not provide positive shuto󰀨 in
dead end service. It is intended for
large distribution systems where steam
leakage will condense before steam
pressure builds up. Downstream piping
and components must be rated for
maximum upstream steam pressure for
dead end service. Failure to do so could
cause personal injury or death.
