Válvulas Hydra

Válvulas Hydra’s 1966 logo by Brazilian designer Alexandre Wollner uses clean, geometric forms to reflect the precision of the manufacturing industry. The mark likely draws on the hydra’s many heads to suggest multiple valves or connections, while its bold, modular style captures the modernist design ethos of mid-century Brazil. It’s a functional, memorable emblem that communicates strength and industrial reliability without unnecessary decoration.
