Válvulas Zubi S.L. has been manufacturing valves since 1979, in the beginning we focused on the exclusive manufacture of diaphragm valves, a field in which the company has earned a prestigious reputation. Later, we expanded our production range and began to also manufacture disk check and ball check valves. We currently offer an even wider range of products which also include knife gate valves, wall penstocks, channel penstocks and square knife gate valves. With more than 30 years experience and its ongoing commitment to improvement, Zubi offers its customers a wide range of products that enables all kinds of solutions for every conceivable need. The main characteristics of our valves are their high quality, their perfect watertightness and their ease of handling. This of course would not be possible without the collaboration of all our staff and the use of equipment and procedures that enable us to ensure both continuity and improvement, as well as the optimisation of costs.
