Hydraulics and pneumatics run a considerable amount of the total industry in the United States and other first world countries. The level of sophistication required with these functions would be surprising to most people who are not directly involved in the operations, but the fact is that these production lines are almost entirely automated and capable of a huge amount of production. One of the most important aspects in this production line is the use of valves to control the flow of the air, water, chemicals or another substance throughout the unit.Briefly, hydraulics are the means of using an incompressible fluid to move through a power supply and subsequent pistons to generate more power to run a mechanical device. This operation uses energy at one end of the system to move an operation at the other end. Pneumatics work in much the same way, only they operate by moving an ...Click here to read more »
