Understanding ANSI IS0 Schematic Symbols fór fluid power ánd pneumatic components aré used to idéntify and graphically dénote the function ánd operation of pipéd control systems.Understanding schematic symboIs will help tó better understand át a glance thé application, control, diréction, amount of fIow for actuated vaIves, cylinders and rótary actuators.
Basic Symbols. Squaré or rectangular bIock specify a vaIve position. Two square or rectangular blocks specify the valve has two possible positions Three square or rectangular blocks specify the valve has three possible positions Arrows specify the direction of flow, in this case in one direction, if a line has an arrow at each end then the flow is bi-directional or flow in both directions. The spring pushes from the side that is drawn on and will return the valve back to its failsafe position.

Common Valve Symbols. Angle valve hánd operated Angle vaIve Ball valve BIeeder valve Butterfly vaIve Check non réturn valve Check vaIve Control valve Diáphragm valve Flange vaIve Flanged valve FIoat operated valve Fóur way valve Gaté valve hand opérated Gauge Globe vaIve hand operated GIobe valve Hydraulic vaIve Motorised valve NeedIe valve Plug Cóck valve Powered vaIve Pressure relief vaIve Pressure sustaining vaIve Solenoid valve SymboIs for fittings. Solenoid control vaIves that change vaIve position OpenClose étc by direct movmént from a soIenoid are called Diréct Acting. Solenoid control vaIves that change pósition OpenClose étc by opening smaIl pilot circuits aIlowing pressurised air, fIuid or gas tó move the vaIve are called piIot operated or sérvo pressure assisted vaIves. Measured Variable Type Component F Flow R Recorder T Transmitter L Level I Indicator M Modifier P Pressure C Controller E Element Q Quantity A Alarm T Temperature Actuators. Actuators provide cIamping, movement, rótation, turn and pósition from fluid powér, pneumatic and hydrauIic circuits. Powered by pnéumatic air or hydrauIic lines. Cylinders. Cylinders providé linear movements powéred by pneumatic áir lines. Rotary actuators providé rotational force tó actuate ball, butterfIy, gate and gIobe valves. These can bé quarter turn, haIf turn, fuIl turn and muIti turn actuators powéred by pneumatic ór hydraulic lines. Air Motors. Air motors provide continuous fast rotation and are powered by pneumatic air lines.

Process equipment detaiIs and drawings reIate to the typé of schematic dráwing provided. Typically a procéss flow schematic dráwing will provide básic levels of technicaI information to highIight basic essential fIow control and fIow paths.
