Tucson Hydrocontrols was started in 1988 with a vision to take the Indian hydraulic industry forward to the 21st century by introducing a new type of cartridge valve that will be required by the earthmoving and construction industry. To secure a solid customer base, Tucson decided to start manufacturing products such as Non Return Valves, Throttle Check valves and Flow Control Valves. Very soon Tucson introduced, for the first time in the country, Overcentre Valves and cartridge type Relief and Pressure Reducing Valves. Tucson soon became the ultimate name in Overcentre Valves and Construction Equipment packages
