There are different types of valves, depending on the task they are designed to perform: directional control valves direct the flow of oil, pressure valves protect against overload, and flow control valves regulate speed. The appropriate valve is selected depending on the machine or requirement. In industry, construction machinery, or logistics, valves reliably control movements—often without us even noticing.

1.1 PRESSURE AND CHECK VALVES

Pressure valves are safety valves in the truest sense of the word: they release excess pressure to the outside before cylinders, hoses, or motors are damaged. Check valves, on the other hand, function more like one-way streets – they only allow fluid to flow in one direction. Both valve types are virtually standard equipment in every hydraulic system, from small machines to large production facilities. They ensure that everything runs smoothly and that components last longer, even when the system is subjected to heavy daily use.

Control and directional valves regulate the flow of hydraulic fluid to specific components. They therefore determine when a cylinder extends or a motor runs. They are typically found in construction machinery, lifting platforms, or manufacturing plants. Their task is simple but crucial: without these valves, movements could neither be controlled precisely nor executed safely. Thanks to clever designs, directional control valves can be operated manually, electrically, or hydraulically—depending on what the machine needs.

2. THE ADVANTAGES OF VALVE TECHNOLOGY IN HYDRAULICS

Valves are small but indispensable. They enable precise control, withstand continuous loads, and work reliably even when dust, dirt, or temperature fluctuations come into play. They can also be flexibly adapted to different loads or processes, giving machine builders a lot of leeway in their designs. Regular maintenance of the valves ensures that the system will function for years to come – without frequent failures and with predictable processes.
