ADCA
ADCA - Specialist for Steam Equipment and Heat Recovery Solutions
Valsteam ADCA has grown up to become steam equipment and valve manufacturers, using the knowledge acquired along the years, and can now assure the complete production cycle: design, machining, welding, assembly, tests, quality and packaging for a very wide range of products.
ADCA has two production facilities with a total covered area of 18 000 m2, located in a small village in the ocean side of Portugal, and are currently growing again, expanding their main production facility. The team today consists of almost 100 people that together drive the Portuguese caravel along the five continents and more than 100 countries.

QUALITY CONTROL AND TESTING
Products are meticulously tested and rigorously controlled throughout the manufacturing process granting the highest level of quality and reliability. From raw material control via spectrometry and 3D measuring to final product testing.
The substantial investment in stage-of-the-art machinery allows us to achieve a high level of quality and reliability, as well as a natural increase in productivity and decrease in delivery times, especially for non-standard series of products.
As One-Stop-Shop and a full service manufacturer, we assure the complete production cycle: design, machining, welding, assembly, tests, quality and packaging.
A complex system that depends on the high technology we use.
