Danval Ind?stria de Equipamentos began its activities in 1954 as a manufacturer and distributor of spare parts for motor vehicles.
In 1958 it entered the electrical market producing and distributing small bells for homes, alarm bells, elevators and mainly acoustic signals to stop request of buses.
In the 60s it began to produce and distribute small bells for telephones and high powered industrial uses.
