Valve Symbols
Valves are used to control the direction, flow rate, and pressure of fluids. Figure 1 shows the
symbols that depict the major valve types.
It shoud be noted that globe and gate valves will often be depicted by the same valve symbol.
In such cases, information concerning the valve type may be conveyed by the component
identification number or by the notes and legend section of the drawing; however, in many
instances even that may not hold true.
