Intro to: Valves


For pipelines to safely operate, they need careful engineered design.

One example is in the selection and placement of valves that let operators isolate and access sections for maintenance and shut down sections of pipelines in emergencies.  

The NEB requires companies to place valves appropriately for pipeline control, and to reduce potential impact of a failure. 

Engineers determine where they're needed. 

Some of the things that are considered when deciding where to place valves are: 

  • surrounding terrain,
  • sensitive areas, and
  • time to close,
  • fluid type, and
  • consequences of a failure.

When valves need to be closed, the preferred method is by remote control from the pipeline control centre, but it could be done manually if necessary.

There are even automatically controlled valves. These are used mainly in gas pipelines.

All pipeline designs follow Canadian national safety standards, as well as professional association and regulatory guidelines. This ensures that high safety and quality standards
