Reference concept: Metering valve needle
Page: https://chengshuoprecision.com/components/shafts-and-pins/metering-valve-needle/

Our component / drawing revision: [ ]
Assembly and mating interfaces: [ ]

Please review:
1. Needle and mating-seat sections with working profile and travel reference
2. Material, treatment, surface finish and inspection requirements
3. Quantities plus defined assembly flow or leakage validation responsibilities

Sample acceptance to agree:
1. Taper profile: Specify angle or profile definition, working length and tip radius.
2. Guided relationship: Relate metering surface to guide journal and axial datum.
3. Adjustment geometry: Define thread, travel references and shoulder positions.
4. Surface and handling: State final surface requirements and protection for the tip.
