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.

5. Carefully vent any remaining internal downstream pressure.
