For the turbine intake gates of hydroelectric power plants hydraulic cylinders are required which can guarantee a reliable load hold function but can also interrupt the water flow at a high speed, to prevent a breakdown of the turbine.

Beside the production of new hydraulic cylinders we can also offer refurbishments and modernizations. For the “Iron Gate” hydroelectric power plant at the river Danube in Romania for example the approximately 30 years old hydraulic cylinders of the turbine intake gates were completely refurbished. On this occasion the original piston rods were refurbished with the Ceraplate rod coating and the cylinder design was changed to Hunter seal and guiding elements.
