Hydraulic circuits can be comprised of an infinite combination of cylinders, motors, valves, pumps and other equipment connected via hydraulic pipes and tubes. The complexity of these components are difficult to represent fully, so a family of graphic symbols have been developed to represent fluid power components and systems on schematic drawings.
Hydraulic symbols are issued and controlled by The International Standards Organization (ISO), standard ISO 1219-1:2012.
The symbols do not identify component size or their actual position on the machine, however the symbols do provide vital information relating to the configurations and flow path connections.
Below we have summarised some of the most common symbols you may come across. Our technical sales engineers will be happy to help should you need any further help and assistance. Please get in touch on +44 (0)845-644-3640.
