  • Control Valves and their Principles of Operation

    Principles of Operation The most common final control element in the process control industries is the control valve. The control valve manipulates a flowing fluid, such as gas, steam, water, or chemical compounds, to compensate for the load disturbance and keep the regulated process variable as close as possible to the desired set point.

  • How do hydraulics work on an excavator?

    The hydraulic system works on the principle of Pascal's law which says that the pressure in an enclosed fluid is uniform in all the directions. The Pascal's law is illustrated in the figure. As the pressure is same in all the direction, the smaller piston feels a smaller force and a large piston feels a large force.
