ASM SIPLACE 00335984 is the blowing-unit valve documented for the DLM1 placement-head pneumatic system. Its service role belongs to the blow-air path and should be kept separate from the vacuum-generation assembly used on the same head generation.
00335989 is separately documented as VACUUM GENERATOR COMPLETE/DLM1. The two P/Ns are numerically close and both sit in the DLM1 pneumatic area, but they represent different documented functions and different repair levels.
00335984 DLM1 Valve Specifications
| Part Number | 00335984 |
| Part Type | Blowing-unit valve |
| Head Generation | DLM1 |
| System Area | Placement-head blow-air / pneumatic path |
| Confusing P/N | 00335989 — complete DLM1 vacuum generator |
| Repair Boundary | Separate blowing-valve diagnosis from vacuum-generation diagnosis |
| Key Matching Point | Confirm exact P/N and DLM1 head configuration |
If a problem is isolated to the blow-air path, inspect the local air supply, hose connection and valve operation before widening the repair to a larger pneumatic assembly. A vacuum-generation problem follows a different path and should not automatically be assigned to 00335984.
This blow-versus-vacuum distinction is the main service value of identifying the P/N correctly. It keeps diagnosis on the affected pneumatic function instead of replacing a neighboring DLM1 assembly because the numbers appear similar.
Send the valve label, DLM1 head information, installation photos and fault description for matching support. Other pneumatic and vacuum components are available under ASM SIPLACE SMT head parts.
