SOLENOID VALVES
The PGC2000 uses two different types of solenoid valves in the Purge Air Panel, a vented type and a
non-vented type (see Figure 4-65). Since these solenoids are not interchangeable, you must ensure
that a replacement solenoid is the same type as the solenoid being replaced.

Vented Solenoid
Non-vented Solenoid
Figure 4-65. SOLENOID VALVES
The non-vented solenoid valve was introduced at sales order number HF01220001 (the sales order
number is listed on the analyzer nameplate). PGC2000 analyzers shipped prior to this sales order
number have the vented solenoid.
