If the control valve comes with a handwheel, is it not necessary to install a bypass line?
Thread Content
The control valves on the large-diameter pipes in our factory are all designed this way – they only have handwheels and no auxiliary lines. Is this done to save money? Does it still not require a secondary line if it has a handwheel?
It must also be related to the process conditions in place
If it has a handwheel, is a secondary line not needed? If that valve breaks, will the machine stop? I can’t help it!
There must be auxiliary lines; if the valves don’t work, it’s a disaster that will affect the production process

It is equipped with a handwheel, allowing manual control in the event of automatic valve failure, thus ensuring normal production. The function of the bypass line is to enable production to continue when the valve is damaged and needs to be removed. The light strip has a knob; it stops working automatically and still can’t be removed. Taking it down will affect a large area.
It mainly depends on what size your caliber is? We don’t have any branch lines for DN150 and above. As for whether to set up a secondary line, it depends on whether there is enough space Process importance? Choose valve reliability? Do you have money? What does the leader mean? It’s actually quite complicated
I think it’s not necessary to use control valves or manual valves; a bypass line is still needed.
Having a bypass line is one thing, while whether a control valve comes with a handwheel is another; the bypass line allows for diversion in case of valve failure, facilitating maintenance of the valve； The handwheel is used for temporary operation when the valve cannot function properly or does not operate fully.
