Graphic Symbols Standards
� Pneumatic symbols conform to and are devised from the International Standard ISO 1219-1 1991
� This covers graphical symbols for Fluid Power Systems and Components
� Port markings for fluid power valves are not covered by the ISO standard. These are taken from the recommendations of CETOP RP 68 P

Pressure regulators
� A pressure regulator symbol represents a normal state with the spring holding the regulator valve open to connect the supply to the outlet.
� The dotted line represents the feedback, this opposes the spring and can vary the flow through the valve from full flow, through shut off, to exhaust. The symbol is usually drawn in only this one state. The flow path can be imagined to hinge at the right hand end to first shut off the supply then connect to the exhaust.

Pressure relief valves
� A pressure relief valve symbol represents a normal state with the spring holding the valve closed.
� Adjustable relief valve simplified
� The dotted line represents feed-forward, this opposes the spring and can be imagined to lift the flow path. When the pressure reaches an excess value the flow path will line up with the ports and flow air to relief.
� Preset relief valve simplified

Valve symbol structure
� The function of a valve is given by a pair of numerals separated by a stroke, e.g. 3/2..
� The first numeral indicates the number of main ports. These are inlets, outlets and exhausts but excludes signal ports and external pilot feeds.
� The second numeral indicates the number of states the valve can achieve.
![Page 38: Simbol Pneumatik _from Norgren](https://reader031.vdocuments.site/reader031/viewer/2022012307/547802045806b5ed188b4705/html5/thumbnails/38.jpg)

� A 3/2 valve therefore has 3 ports (normally these are inlet, outlet and exhaust) and 2 states (the
normal state and the operated state)
