When considering what types of valves are suitable for installation in bypass piping, it is necessary to think about the role of the bypass line. What was the purpose for the installation of that particular bypass line? Bypass piping can roughly be divided into two categories.

 

Bypass piping that acts as a backup line to allow operation to continue while damaged equipment such as pressure reducing valves and steam traps are isolated and shutdown during replacement or repair

Bypass piping whose purpose is to supplement the performance of pressure reducing Valves and traps

 

These different objectives require valves with different features. Therefore, the optimal valve models will be different.
