WARNING

In the case of a downstream line break,

numerous factors affect the capability to

evacuate gas from the pipeline. These

factors include the distance of pipe to the

break, the diameter of the pipe, size of the

break and the number of restrictions, such

as valves, elbows and bends, downstream

of the regulator and/or slam-shut device.

Due to these factors additional protections

should be installed to stop ow in the

event of a line break.

Shutdown

Installation arrangements may vary, but in any

installation it is important that the valves be opened

or closed slowly and that the outlet pressure be vented

before venting inlet pressure to prevent damage caused

by reverse pressurization of the regulator. The following

steps apply to the typical installation as indicated.

1. Open valves downstream of the regulator.

2. Slowly close the upstream shut-off valve.

3. Inlet pressure should automatically be released

downstream as the regulator opens in response to

the lowered pressure underside of the diaphragm.

4. Close outlet shut-off valve.
