Hydraulic control systems must be designed in such a way that, as far as possible, there is no danger to people or the environment. Such control functions in hydraulic systems are implemented with hydraulic blocks in which the necessary valves and control units are compactly housed.

Machines or aggregates whose function is impaired by unchecked vibrations can cause serious consequential damage or cost-intensive downtimes. The hydraulic vibration dampers from Hänchen prevent the development of such vibrations.

If hydraulic cylinder housings or other oil chambers are not pressurised, there is a risk of foreign bodies getting into the interior of hydraulic systems through inflowing air. These can cause major damage. This can be prevented with exhaust port filters that allow the air to escape.

The multi-channel rotary feedthrough offers a solution for the transfer of fluids between a fixed and a rotating assembly. These are particularly used in machines and other precise, fast-rotating systems. The fluid is fed into rotating channels and passes through these into the rotating body. Possible fields of application:

• Coolant supply in tool spindles
• Supply of hydraulic cylinders on rotating portals
