5.2 Purge Valve Adjustment
The purge flow control valve must be set according to the inlet pressure of the dryer. The valve must be opened to the
corresponding number of turns referenced in the table below.

Always base the pressure adjustment on the lowest operating pressure of the system
The procedure for adjusting the purge flow control valve is as follows:

The purge control valve should be set during initial installation & setup and then not adjusted further unless the
operating pressure changes or other problems arise.
1. Begin by fully closing the valve. Rotate the knob clockwise until rotation stops.
2. If no reference mark exists, use a permanent marker to make two aligned markings on the valve stem
and valve body indicating the closed position.
3. Referencing a calibrated flow meter, rotate the knob counter clockwise in 1/8 turn (45 degree)
increments until the desired flow rate has been achieved, counting each time a full rotation has been
made.
4. Record the standard system pressure and valve setting in this manual for future reference. A blank
table has been provided below for this purpose.
5. At a minimum, the purge control valve must allow enough airflow to fully repressurize the dryer during
the 4 minuet repressurization phase. This should be verified using the lowest observe system dryer
inlet pressure.
