The purpose of this system may be to control where fluid flows (as in a network of tubes of coolant in a thermodynamic system) or to control fluid pressure (as in hydraulic amplifiers).Hydraulic circuit - WikipediaSee all results for this question CHAPTER 4: ISO Symbols | Hydraulics & Pneumatics Either symbol set (ANSI or ISO) may be -- and is -- used in the United States. However, many companies today use the ISO symbols as their standard for work with foreign suppliers and customers. The following pages go through all standard ISO symbol information as it applies to hydraulic and pneumatic schematics.Author: Bud Trinkel[PDF] The Secret of Hydraulic Schematics - iranfluidpower Reading and Interpreting Hydraulic Schematic Symbols Page 11 Sullivan Pressure Control Symbols Hydraulic pressure is controlled through the use of valves valves that open and close at different times to allow fluid to be bypassed from points of high pressure to points of low pressure.
