GP-2000-R Startup and Adjustment Procedures

Improper adjustment of the pressure reducing valve may cause hunting, improper control and possible damage to the

valve itself. Adjust the valve as follows:

1. Close the gate valves before and after the pressure

reducing valve and blow fluid through the by-pass line.

After draining, be sure to close the by-pass globe

valve.

2. Turn the adjusting screw clockwise to close and

counterclockwise to open.

3. Close the pilot valve before opening up the steam inlet

valve.
