Trident AS079B Exhaust Valve Solenoid Pilot Valve
Genuine Trident AS079B solenoid pilot valve for the exhaust valves on Dryspell Plus modular heatless desiccant air dryers. One part number covers the entire range from size 10 through size 375 SCFM. The pilot valve takes the electrical signal from the dryer controller and delivers the air signal that strokes the main exhaust valve.
Because it is the link between the controller and the valve, a failed pilot valve looks exactly like a much bigger problem. The dryer stops venting the regenerating tower, the dew point climbs, and the controller shows a normal cycle the whole time. Checking the pilot valve before condemning a controller or a main exhaust valve assembly saves considerable time and money.
Specifications
- Trident part number: 8059240398 (AS079B)
- Function: Solenoid pilot valve for the main exhaust valve
- Fits: Trident Dryspell Plus sizes 10 through 375 SCFM
- Quantity: Each dryer uses two, one per tower
Signs the pilot valve has failed
- Tower will not depressurize even though the controller has stepped the cycle
- No audible click at the pilot when the exhaust step should begin
- One tower purges normally and the other does not
- Coil reading open circuit or drawing no current
Diagnose in this order
Confirm the pilot valve first, then the main exhaust valve, then the controller. Each dryer carries two pilot valves, so if one has aged out the other is usually close behind and worth replacing at the same visit.
Isolate air and electrical supply before removing the valve, and follow the Trident Dryspell service manual for the correct procedure.
NOTE: Actual product may be different from pictured!
