Pipeline valve symbols are used to represent different types of valves in schematic diagrams and other engineering drawings. These symbols are standardized by the American Society of Mechanical Engineers (ASME) and are used in a variety of industries, including oil and gas, chemical, and manufacturing.

Pipeline Valve Symbols

There are a number of different types of pipeline valve symbols, each of which represents a specific type of valve. Some of the most common valve symbols include:

  • Ball valve: A ball valve is a type of valve that uses a ball with a hole in it to control the flow of fluid. The ball valve symbol is a circle with a cross in the middle.
  • Butterfly valve: A butterfly valve is a type of valve that uses a disc to control the flow of fluid. The butterfly valve symbol is a circle with a line through the middle.
  • Gate valve: A gate valve is a type of valve that uses a gate to control the flow of fluid. The gate valve symbol is a rectangle with a line through the middle.
  • Globe valve: A globe valve is a type of valve that uses a globe to control the flow of fluid. The globe valve symbol is a circle with a cross in the middle.
  • Needle valve: A needle valve is a type of valve that uses a needle to control the flow of fluid. The needle valve symbol is a circle with a line through the middle.
  • Plug valve: A plug valve is a type of valve that uses a plug to control the flow of fluid. The plug valve symbol is a circle with a line through the middle.
  • Relief valve: A relief valve is a type of valve that is used to release excess pressure from a system. The relief valve symbol is a triangle with a line through the middle.

In addition to the basic valve symbols, there are also a number of other symbols that are used to represent more specific types of valves. These symbols include:

  • Check valve: A check valve is a type of valve that prevents the flow of fluid in one direction. The check valve symbol is a circle with a slash through it.
  • Diaphragm valve: A diaphragm valve is a type of valve that uses a diaphragm to control the flow of fluid. The diaphragm valve symbol is a circle with a line through the middle.
  • Pressure regulator valve: A pressure regulator valve is a type of valve that is used to regulate the pressure of a fluid. The pressure regulator valve symbol is a circle with a line through the middle.
  • Solenoid valve: A solenoid valve is a type of valve that is operated by an electric current. The solenoid valve symbol is a circle with a line through the middle.

Pipeline valve symbols are an important part of engineering drawings and schematics. By understanding the different types of valve symbols given in below figure, you can better understand the flow of fluid through a system.

Pipe Fitting Valves Symbols

Pipe fitting valve symbols are used in schematics and diagrams to represent different types of valves used in piping systems. Valve symbols provide a standardized way to convey valve information quickly and easily. Common valve symbols include circles to represent gate valves, triangles for globe valves, and squares for ball valves.

The symbols typically show the direction of flow through the valve and may also indicate other valve features like actuators or handles. Having a standard set of valve symbols allows piping engineers, designers and technicians to interpret piping diagrams consistently and accurately.
