What valve goes with a diaphragm pressure gauge?
Thread Content
The fluid in the pipeline is corrosive and prone to clogging; therefore, a diaphragm pressure gauge was chosen for pressure measurement. However, all diaphragm pressure gauges come with DN50 flanges, and the gate valve I selected also has a DN50 size. I would like to ask everyone: what kind of valve is generally used in such cases?
Install a ball valve or globe valve below the lower flange
It is usually a globe valve or a ball valve.
If it is prone to clogging, ball valves are used
A globe valve will work; that’s what we use. However, the pipe diameter is DN25.
Thank you! It seems that both ball valves and globe valves will work
There are diaphragm valves; I have chosen ones for the desulfurization tower
