Quality control is applied throughout our production and inspection process. All products are visually inspected before delivery, and sampling inspections include dimensional tolerance, surface roughness, material verification and valve pressure testing — so buyers receive reliable, consistent sanitary stainless steel components.
Quality checks run from incoming material through final packing. Sampling inspections and a full visual check before delivery help reduce defects and improve consistency.
We verify material consistency and inspect key product dimensions against drawing tolerances before machining is released.
Surface finish is checked (Ra) on sampling basis to confirm cleanability and hygienic-grade requirements.
Sanitary valves can be pressure-tested according to product requirements before delivery.
Material grade (304 / 316L) is verified; PMI and material certificates available on request.
Every product receives a visual inspection before shipment to reduce visible defects and improve delivery quality.
Products are cleaned and protectively packed to prevent damage and contamination in transit.
Sampling inspections cover the dimensions and characteristics that matter most for sanitary processing reliability.
Key OD/ID, length and connection dimensions checked against drawings.
Inner/outer surface finish measured to confirm hygienic cleanability.
Grade confirmation (304 / 316L); PMI and 3.1 certificates on request.
Seat and shell pressure performance tested to product requirements.
100% visual inspection for finish, welds and cosmetic defects before packing.
All products carry a one-year warranty against quality issues.
On request we provide material test certificates (EN 10204 3.1), dimensional and surface finish records, and inspection reports to support your incoming QC and validation.
