What is the difference between a vent valve and a breather valve?

Can a breathing valve replace a vent valve? Last edited by chengkang on 2009-4-24 20:19 in this post.]
I don’t think it’s possible; a breathing valve is used to regulate the pressure balance between the inside and outside of the container, while a vent valve is used to release pressure from within the container. Their functions are not identical, so they cannot replace each other. Moreover, some containers require a certain level of pressure or vacuum, making substitution even more impossible
These two types of valves have different functions and are installed in different locations as well. Only the general solution storage tanks on our equipment are equipped with breather valves, while pressure vessels are fitted with vent valves.
They serve different purposes; the breathing valve is used for storage tanks, while the vent valve is used for pressure vessels
It cannot be used universally; the function of a breathing valve is to maintain constant pressure and prevent the storage tank from developing a negative pressure, which could lead to accidents. The vent valve is used for purging and ventilation. In the case of atmospheric-pressure tanks, a breathing valve can be used as a substitute for a vent valve; their functions are the same. However, in the case of pressure vessels, a breathing valve cannot replace a vent valve
What was said upstairs is correct. Also, the vent valve is equipped with a manual valve, while the breather valve is installed directly on the equipment
