For water level control as well as for flood protection in modern dams hydraulic drive systems with hydraulic cylinders are mainly used for gate movement and positioning. Due to the different cinematic of the used radial gates, rotary gates, slide gates and flap gates the hydraulic cylinders have to be engineered according to the respective case. This can be done according to the usual DIN and ASME standards but also regional standards as well as special customer requests can be considered. The necessary functions for load holding, synchronisation and safety will be realized with manifold blocks which are mainly direct flanged to the hydraulic cylinders. Through the optional possible engineering and production of hydraulic manifold blocks as well as of the associated power packs we can offer our costumers complete systems solutions for civil engineering. An actual reference list, representing our decades of experience from more than 100 projects, is available on request.
