Fluid power systems are those that transmit and control power through use of a pressurized fluid (liquid or gas) within an enclosed circuit. Types of symbols commonly used in drawing circuit diagrams for fluid power systems are Pictorial, Cutaway, and Graphic. These symbols are fully explained in the
Our free downloadable PDF series includes hydraulic symbols for lines, pumps, motors, cylinders, accumulators, valves and other basic symbols
iso 1219-1 covers graphic symbols for both hydraulic and pneumatic equipment. For circuit diagram layout rules see bs iso 1219-2.

This part of ISO 1219 supplements ISO 1219-1 and ISO 1219-2 by specifying rules for the generation and combination of symbols of connectable components in circuit diagrams. Using these symbols, the design envelope and piping can be reduced.

ISO 1219-1:2012 establishes basic elements for symbols. It specifies rules for devising fluid power symbols for use on components and in circuit diagrams. ISO 1219-1:2012 is a collective application standard of the ISO 14617 series.
In fluid power systems, power is transmitted and controlled through a fluid (liquid or gas) under pressure within a circuit. Graphical symbols are intended to describe fluid power components and their function.
