ATS Beta-Press 316L Ball Valves — Laser Marking Verified at the Production Station
Luckee conducted an inline inspection during active production of the ATS Beta-Press 2-piece stainless steel ball valve range — observing the laser engraving station live, verifying brand, batch code, and 316L material grade on individual valve bodies, and confirming dimensional and packaging compliance before shipment.
What This Inline Inspection Covered
The ATS Beta-Press ball valve is a 2-piece stainless steel press-fit isolation valve designed for direct integration into press-fit pipework systems — no threading or soldering required. For a product carrying a brand mark and rated to PN25, the quality of the laser engraving and the accuracy of the material grade declaration are critical: a mismarked material grade on a live plumbing system can create liability for the installer and the supplier.
This inline inspection focused on four verification points: laser marking quality at the production station, dimensional accuracy of the press-fit ends, material grade visibility and legibility, and packaging integrity from inner poly bag through to outer carton labelling. Both SKUs in the current production run were inspected — the 22mm (BP-V-2P-PP-22) and 54mm (BP-V-2P-PP-54) sizes.
Laser Marking Verified Live at the Production Station
The inspector was present at the fiber laser marking machine while active production was underway. Each valve body was placed in a custom-made wooden jig aligned under the laser head, and three distinct marks were applied per unit. All three marks were verified for legibility and correct content before the batch was cleared for packaging.
Four Verification Points — All Passed
Each verification point was documented with photographs taken at the time of inspection.
DN50 PN25 Body Marking — Embossed Casting
Dimensional Check — 150.68mm Overall Length
Inner Packaging — Individual Poly Bag Per Unit
Outer Carton Label — SKU, Size, Qty, Weight
Laser Mark Consistency Across Production Batch
Pallet Presentation — Strapped and Shrink-Wrapped
Hydrostatic Pressure Test — Water Bath Submersion
Test Bench — Dual Calibrated Pressure Gauges (0–1.6 MPa)
Press-End OD — 28mm Valve: 28.78mm

Passed — Cleared for Shipment
All four verification points passed. Laser marking was observed live at the production station and confirmed correct on all three marks (brand, batch code 24-11, material grade 316L). The DN50 PN25 embossed casting markings are correct and legible. Overall body length of 150.68mm on the 54mm SKU falls within dimensional tolerance. Individual poly bag inner packaging and outer carton labelling were both confirmed correct and consistent with the ATS Proequipment purchase order specifications.
