INCORPORATED SB/82 SLAM-SHUT VALVE

This is a device (fig. 9) which immediately blocks
the gas flow if, following some kind of failure, the
downstream pressure reaches the set-point for its
intervention, or is operated manually.
On the REFLUX 819 regulator, it is possible to have
the SB/82 slam-shut incorporated both with the
service regulator and on the one functioning as in-line
monitor.
The main characteristics of the slam-shut device are:
