Valve to control ammonia pressure?
Thread Content
One of our client’s laboratories has a container containing ammonia gas and ammonia solution; the ammonia gas is located in the upper part of the container. It is necessary to maintain the pressure inside this container between 0 and 6 bar. What type of valve would be suitable for this purpose? A safety valve? Ammonia.

Install a gas pressure regulator at the air inlet, and then attach a precision pressure gauge with a range of 0–1.6 Mpa at the very top of the tank. That will meet your requirements! Hehe, I used to work with this kind of equipment!
Revise it! I just saw that your required pressure range is 0-6 Mpa; in that case, you’ll need to choose a pressure gauge with a larger range, at least one with a range of 0-10 Mpa. A safety valve also needs to be installed between the intake pipe and the tank (provided that water is also added inside the container). If the bottle is emptied every time water and air are introduced, then it’s not necessary.
Moderator, come in! Please help to make the changes. I made a mistake; a precision pressure gauge with a range of 0-1 Mpa will suffice for the pressure gauge I misread it! Thank you!
