Bypass Valve

Definition - What does Bypass Valve mean?

A bypass valve is a type of valve that is installed in a bypass pipeline. These valves generally do not indicate any particular category, shape or size of the valve. Therefore, valves that are installed on the bypass piping line, such as pressure reducing valves, steam traps and control valves, are also known to be bypass valves.

Petropedia explains Bypass Valve

An installation engineer should first understand the purpose of the bypass line before installing a bypass valve onto it. In the oil and gas industry a bypass piping line is laid for two reasons:

  1. To act as a backup line so as to allow continuous operation in case any failure or damage occurs to the main pipeline equipment
  2. To supplement the performance of the mainline valves
