How AVK Deep-Engraves Valves for Saudi Desert Service with the 200W M7
Permanent identification on hard valve steel that has to stay readable after years under Saudi Arabian sand, heat and abrasion. Production reference from the AVK Group.
A valve buried in desert infrastructure cannot be dug up because its label faded. When a valve group like AVK specifies deep laser engraving for identification, the mark has to outlive paint, plates and stickers — by decades.
About AVK
The AVK Group is a family-owned Danish company founded in 1941 in Galten, Denmark, and one of the world’s leading manufacturers of valves, hydrants and fittings for water supply, gas distribution, wastewater treatment and fire protection. The group operates sales companies and factories across the globe — including AVK Saudi Valves Manufacturing Co. (AVK SVMC) in Jeddah, established in 1985, which has produced more than 700,000 valves and 100,000 fire hydrants for the region.
The problem AVK needed to solve
Valves installed in Saudi Arabia live in one of the hardest environments a metal part can face: abrasive wind-blown sand, extreme heat, and decades of service underground or in exposed installations. Surface-level marks — printed labels, shallow etching, attached plates — tarnish, wear off or disappear. For traceability and maintenance, the identification on the valve body has to be engraved deep into the hard valve steel itself, so it stays readable for the life of the part.
The second requirement was speed. Valve bodies are large, the steels are hard, and production volumes are industrial. A marking process that is permanent but slow becomes the bottleneck of the line.
The machine
AVK runs the 200W MOPA M7 fiber laser for this work. At 200 watts, the M7 source removes material fast enough to cut deep, clearly defined identification into hard valve steels without multi-hour cycle times — the deep-engraving speed on their steel is what AVK is happiest about. The order grew to several machines, including units for the AVK Saudi Arabian operation, putting the engraving capability in the same region where the valves are built and installed.
What AVK produces with the machines
- Deep-engraved valve identification — type, size and traceability marks cut into the body, deep enough to survive sand abrasion without tarnishing into illegibility.
- Permanent marks on hard steels — no consumables, no plates to rivet, no labels to replace in the field.
- Production-speed cycles — 200 watts of MOPA power keeps deep engraving compatible with industrial throughput.
Why this matters when you evaluate a laser machine
Anyone can mark steel. The questions that separate machines are how deep, how fast and on which steels. A global valve manufacturer choosing a 200W M7 for desert-service engraving is a useful benchmark: if your parts are hard, your environment is abrasive and your volumes are real, this is the power tier where deep engraving stops being the slow step. If your work is lighter, the 100W M7 covers deep engraving at smaller scale — and our engineers will tell you honestly which tier your parts need.
