Control valve bypass

This post was last edited by sunjl1981 on 2013-1-6 at 23:13. Most control valve systems in chlorine engineering design lack bypass lines – is this reasonable? What have you all seen? Have you used the bypass lines for control valves such as those used for brine injection and differential pressure control? # ， ， &
What is the purpose of the side plot mentioned by the poster? Redundancy? Or adapt to different control ranges?
Does the term \"secondary line\" refer to the bypass system of control valves? Nowadays, many control valves in imported units basically do not have a bypass system.
