For multi port valves such as 3 way and 4 way the structure of the symbol is similar having a triangle to represent each port or way.

3 way ball valve symbol. Valves are appointed with two numbers for example a 2 2 way valve. Three way ball valves simplify gas and fluid flow control. A 2 2 way valve has two pipe connections inlet and outlet and two switching states open and closed. These check valves can be swing check or lift check valve.

The circular symbol with a two lines at a 90 degree angle is a 3 way ball valve. Similarly the next two symbols are for three way and four way valve. For example the note 2 300 rf pb indicates that the p id calls for this valve to be a 2 ansi 300 raised face piston balanced valve. Symbol for electrical diagrams.

As the name suggests these valves come with a drain port. Subsequent two symbols are of a check valve and stop check valve. This post looks at design differences between l pattern and t pattern flow plus how handle position and range of rotation combine with porting to control flow. 3 way and 4 way ball valves can contain additional detail that defines the type of ball drilling which is either a t or l port ball.

The next symbol is of the excess flow valve. Ball valves straight through 2 2 way 20 angle seat 2 2 way 12 sample schematic example 5 symbols for accessories 8 symbols for position and process controllers for process valves 10 globe valves straight through diaphragm valves full bore 2 2 way 19 ball valves multi port 3 2 way with t passage 21 ball valves multi port 3 2 way with. For faster assembly of block and bleed valve arrangement. To be used for pipes joining at an angle.

Circulator with isolating flanges. The symbol shows three port connections and the two lines connected are shown in the normal position. The choice of flow pattern or valve ball porting t port vs l port provides specific options. These details may include the size function pressure rating and connection type of the valve.

Integrated block and bleed valve. It can be a plug or ball valve. Float operated valve symbol. The second number is the number of switching states.

The first number indicates the number of connection ports. Motorized 4 way valve. 3 2 way solenoid valve symbol. An engineer may also include specific details below the control valve symbol.
