Type OSE Slam-Shut Valve Installation Schematic
Verify that the limits of utilization correspond
to the appropriate operating conditions.
Verify that the safety manometric box (BMS)
and spring correspond to the appropriate
operating conditions on the outlet side of the
regulator.
The equipment should not receive any type
of shock, especially the release relay.
The user should verify or carry out a
protection adapted to the environment.
Fire, seismic and lightening are not taken
into consideration for standard regulators.
If required, a special product selection and/
or speci
fi
c calculations may be supplied
according to speci
fi
c requirements.
If the slam-shut is classi
fi
ed under operating
class B the BMS diaphragm should be
checked periodically.
