Purge Pressure setting

The purge orifices are specific for the size and the operating pressure of the air treatment unit.
If the operating pressure is different from the pressure for which the dryer was ordered, the purge
orifice may have to be adapted.
Purge orifice PD3 type
Reference figure 4.13 and the Purge Plug Identification Table.
•
Each dryer is pre-set with the correctly sized purge valve for an operating pressure of 7
•
barg (100 psig) at point of order.
The lettering (A through S), located on the purge valve body, indicates the orifice size
•
selected to suit the operating pressure of the dryer per the chart below.
• If the inlet pressure to the dryer will be different than the pre-set orifice size, the purge
valve can be adjusted.
• Most dryers use a single orifice purge valve represented by the Blue and Green single
letter references in the table below.
Larger dryers may require a two or three hole purge valve as represented by the Red
•
and Yellow two and three letter references.
To select the correct orifice size, locate the appropriate dryer model at the left side of the
•
table and then the operating pressure
at the top.
•
Make sure that the correct valve body (1, 2 or 3 hole) and orifice disc (01, 02, 03 or 04)
•
has been supplied with the dryer. The
discs have the number (01, 02, 03 or 04) stamped out at the top.

Verification:
Before the installation is going to be used, a validation of the air quality according
pharmacopoeia must be done. These records must be kept by the user at all times.
The electrical wiring must comply with the local regulations. The air treatment unit must be
earthed and protected by fuses against short-circuiting. Consult the electric diagram delivered
with the unit.
Before switching on the main power supply, check the voltage requirements in the technical
specifications or on the unit's data plate.
