Dervos owns the workshop for cast steel/stainless steel/duplex steel gate, globe, check and ball valves.
We purchase high-quality castings and have professional engineer and skilled workers to take charge of the whole process from machining, drilling, pickling, polishing to assembling. After pressure testing, the products will get through out-looking rechecking/defect repairing before painting/coating. When all the processes are done, the valve products need to be inspected strictly by our inspectors before package and delivery.
Our most stable support comes from our skilled workers. Because of their diligence and hard-working, our workshop can fullfill the production on time and keep the good quality always.
