There are numerous hydraulic systems that make use of valves such as:
Industrial Machinery
- Hydraulic Presses: In metal forming, hydraulic presses employ high-pressure valves to regulate the flow and pressure of hydraulic fluid for accurate operation.
- Injection Molding Machines: Different types of valves are used in these machines to control fluid pressures and rates of flow, thereby affecting the speed and accuracy of the molding process.
Automotive Systems
- Power Steering: Hydraulic power steering systems often contain hydraulic valves which can change how much fluid flows between the steering gear and a pump based on how fast or heavy it is being turned.
- Brake Systems: Some large trucks still use hydraulic brakes; in these cases, controlling valves normalize the brake fluid pressure used.
Aerospace & Aviation
- Landing Gear: The extension and retraction of landing gear on aircraft is controlled using hydraulic valves.
- Flight Control Systems: In bigger planes, there are actuators which move control surfaces like ailerons, elevators, rudders that are controlled by hydraulics through their respective valves.
Mobile Equipment
- Construction Machinery: Hydraulic valves play a significant role in lifting equipment such as excavators, cranes and loaders among others.
- Agricultural Equipment: Hydraulic systems in tractors and combine harvesters have various applications including lifting ploughs and adjusting harvester settings respectively; all done through their corresponding valve sets.
Marine Systems
- Steering Systems: Rudder movement on boats or ships is usually actuated by hydraulics involving the application of some valve technology during control actions.
- Winches & Hoists : Sometimes heavy objects have to be lifted up or down using hydraulics where some Valves will also be necessary for smooth operation safety purposes .
Utility Services
- Garbage Trucks : Typically garbage truck’s back-end lift mechanism has got hydraulic valves for compactor controls ,lift controls etc..
- Fire Trucks : The ladder extension as well as pumping system inlet/outlet water functionalities are implemented through hydraulic valves.
Specialized Equipment
- Medical Devices: Sophisticated medical devices such as surgical tables may employ very tiny hydraulic valves for accurate control.
- Simulators : Motion platforms for flight and driving training simulation often rely on hydraulics controlled by valves.
Renewable Energy
- Wind Turbines: To ensure that the blade can be pitched or yawed, some modern wind turbines use hydraulic systems which require precision valves for these adjustments.
In conclusion, hydraulic systems from heavy industrial machinery to daily life utility service and special equipment have benefited greatly from the presence of hydraulic valves in them. They enable this system to deliver predetermined performance and safety standards by regulating flow, pressure as well as directing its movement.
