Válvulas Zubi S.L. has been manufacturing valves since 1979, initially focusing on the exclusive production of diaphragm valves and later expanding its range to include knife gate and check. Their wide array of products includes square fabricated valves as well as many customized variations made to order.
Seal rings and packings on the valves specified to suit the application, media, concentration, and temperature. These valves are used in applications involving powders, suspended solids, and fluids, making them suitable for under-hopper applications where media can fall away from the seat area.
The ZUBI S200 Uni-directional and S700 Bi-direction valves are stocked as standard. We offer sizes ranging from 50 to 400 mm in Cast Iron and Stainless Steel, with PN10/16 flanges, handwheel, cylinder, and ISO top operation.
