Start-up of an automatic control valve requires that proper procedures be followed. Time must be allowed for the valve to react to
adjustments and the system to stabilize. The objective is to bring the valve into service in a controlled manner to protect the system
from damaging over-pressure.
1. Clear the line free of slag and other debris.
2. Install the valve so that the FLOW ARROW marked on the valve body/tag corresponds to flow through the line.
3. Close upstream and downstream isolation valves.
4. Open the isolation ball valves in the control tubing if so equipped. Failure to open these will prevent the valve from functioning properly.
5. Install pressure gauges at locations upstream and downstream of the valve.
