Hydraulic & Pneumatic

Pneumatic systems are typically used in construction, robotics, food manufacturing and distribution, conveying of materials, medical applications (dentistry), pharmaceutical and biotech, mining, mills, in buildings, and tools in factories. Hydraulics is used for the generation, control, and transmission of power using pressurized liquids. The following equipment is required for a hydraulic system: hydraulic fluid, cylinder, piston, pumps, and valves that control the direction of flow, which is always in one direction. They are used in a variety of everyday machine applications: Elevators, Dams, machine tools of hydraulic presses, hoppers, cylinders, and rams, Turbines, lifts, Excavating arms for diggers, braking system.
