At our facilities in El Puig (Valencia), we operate a fully equipped workshop for machining, assembly, adjustment, and after-sales service of industrial valves, accessories, and systems, including:
– Conventional and CNC milling machines and lathes
– Equipment for cutting, drilling, lapping, threading, and various welding technologies
– Test benches, precision tools, and equipment for final adjustments

Unlike other companies in the sector, COMEVAL has followed a reverse path:
We began as a distributor in the 1970s, gaining deep insight into real plant needs and the demands of the market.
The next step was establishing a widely recognized after-sales service, known for its speed and excellence.
In the past 25 years, we have taken an increasingly active role in manufacturing, incorporating our own designs and quality criteria, while adding significant technical capabilities to our structure.
In addition to our rigorous selection of foundries and extensive experience in assembly, testing, after-sales service, and custom solutions, we now offer strong in-house machining capabilities and a robust network of local subcontractors. This allows us to ensure quality, lead time control, and flexibility in the production of components for our private brands UNIFLOW®, UNIWAT®, and DIAVAL®
.
COMEVAL merges field knowledge with design and manufacturing capacity to deliver reliable, proven solutions tailored to every need.
