Pumps
Hydraulic pumps deliver high-pressure fluid flow to the pump outlet. Hydraulic pumps are powered by mechanical energy sources and use gears, vanes, pistons or other devices to pressurize fluid. A hydraulic pump, when powered by pressurized fluid, can rotate in a reverse direction and act as a motor.

Motors
Hydraulic motors are powered by pressurized fluid and transfer rotational kinetic energy to mechanical devices. A hydraulic motor, when powered by a mechanical source, can rotate in a reverse direction and act as a pump.

Valves
Pressure control valves are used to control and regulate pressure in fluid power systems. The maintenance or lowering of pressure can be achieved a number of ways.

Cylinders
Hydraulic cylinders are actuation devices that utilize pressurized fluid to produce linear motion and force. Hydraulic cylinders are used in a variety of power transfer applications.
