All-round valve technology We have the best possible answers when space is at a premium and the requirements imposed on safety and controllability are exceptionally high. Our range embraces everything from spool and poppet type actuating valves to cartridge valves, proportional valves and servo valves. Numerous valves are also available in sea water resistant and explosion proof versions. Advantageous compact control blocks Grouping together several functions on control panels saves pipe work, reduces the amount of space required, and results in a reduction of possible leakage points. High-precision supply pumps Our pressure and power controlled axial piston pumps have proven at control and handling functions. Series A4VS, A4CSG and A10VS are used, depending on the size of the tunnel boring machines. Load sensing circuits are suitable for smaller systems. Control Hydraulics – to Keep Everything Safely Under Control Complete pump stations Our largely standardized pump and tank stations provide an optimum basis for high efficiency as well as reliability. We design and manufacture customized units for particularly tight and narrow installation spaces. Complete systems Our numerous drive elements, pumps, motors, hydraulic cylinders and pressure supply units serve as the starting-point for planning and manufacturing complete systems as well as sub-systems for special duties.
