Flowcharts are valuable in analyzing, documenting, and communicating processes or decision-making steps. They provide a visual representation that enhances understanding and helps in efficient planning and troubleshooting. Process flow diagrams (PFDs) are a specific type of flowchart that outline the sequence of operations required to transform inputs into desired outputs. In this article, you will gain valuable insight into process flow diagrams. You will also learn how to create a process flow diagram online.

Part 1: When to Use a Flowchart?
Flowcharts find applicability in a diverse range of scenarios, primarily serving as a graphical representation of a process. Creating a flowchart online is notably advantageous when attempting to analyze, document, or communicate a series of steps or a decision-making process.
Part 2: What is a Process Flow Diagram?
A process flow diagram (PFD) is a visual representation of the major components, steps, and equipment involved in a particular process. It provides a comprehensive outline of the sequence of operations required to transform inputs into desired outputs. By illustrating the flow of materials, information, or energy, PFDs enhance process understanding, allowing for efficient planning, optimization, and troubleshooting.

Part 3: Process Flow Diagram Symbols – Equipment
In a process flow diagram, equipment symbols represent physical devices involved in the process. These PFD symbols vary depending on the industry and specific context; however, they generally include representations of machinery, vessels, tanks, containers, or any apparatus that contributes to the overall process. An online flowchart maker can enable users to use equipment symbols in a PFD.
Part 4: Process Flow Diagram Symbols – Valves
Valve symbols within a process flow diagram indicate the presence and positioning of valves in a given system. Valves serve as control mechanisms, regulating the flow, pressure, or direction of fluids or gases. When you create a process flow diagram online, valve symbols should illustrate the specific type of valve employed, such as a gate valve, globe valve, ball valve, or any other variation.
Part 5: Process Flow Diagram Symbols - Piping Lines
Piping lines depicted in process flow diagrams provide information about the interconnected pathways through which materials or fluids travel. These symbols represent the various types of pipes utilized in the system, such as straight pipes, bends, tees, or reducers.
Part 6: Process Flow Diagram Symbols – Instruments
Symbols representing instruments in process flow diagrams highlight the instruments used for measurement, control, or monitoring purposes. These symbols encompass devices such as flow meters, pressure gauges, or any other instrument relevant to the specific process.
Part 7: Process Flow Diagram Symbols – Centrifuges
Centrifuge symbols in a process flow diagram flowchart online designate the presence of centrifugal devices involved in separating solid and liquid components or different phases of a substance. Centrifuges find application in various industries such as chemical processing, wastewater treatment, and pharmaceutical production.
Part 8: Process Flow Diagram Symbols - Heat Exchangers
Heat exchanger symbols in process flow diagrams showcase the integration of devices responsible for transferring heat between two or more fluids. These symbols provide information about the type of heat exchanger employed, which can be a shell-and-tube, plate, or air-to-air heat exchanger, among others.
Part 9: Process Flow Diagram Symbols – Crushers
Crusher symbols within a process flow diagram online indicate the presence of crushing or grinding equipment and are used to reduce the size of materials. These symbols depict devices such as crushers, grinders, pulverizers, or any other machinery involved in the comminution process.
