Figure 4-5 – INLET VALVE
Inlet Valve (Body) Inspection -
The valve does not require maintenance or lubrication. If air/oil leaks
develop across the valve disc during pressurized conditions (e.g., machine stopped), valve seals should
be inspected for wear and tear signs:
1. Be sure the unit is completely off and oil sump is depressurized.
2. Disconnect, lockout and tagout power supply to the compressor package.
3. Close (when provided) valve isolating compressor package from air system.
4. Identify (by position) each tube connected to the valve body and remove.
5. Remove four bolts (7) securing valve body to compressor body and remove valve.
6. Inspect poppet seal (o-ring) (5) for wear and tear. Replace, if necessary.
7. In case of noted malfunction (e.g., valve will not open/close properly with good air signal),
proceed to dismantle internal blow-off valve.
•
Carefully lift and remove poppet (3).
•
Remove lock ring (13).
•
Pull cover (9) and inspect seals (10 & 11) for wear and tear. Replace if necessary.
•
Re-assemble blow-off valve in reverse order.
8. Reassemble inlet valve in reverse order.
