Can a diaphragm valve be used for regulation?
Thread Content
Diaphragm valves are generally suitable for use with anti-corrosive, acidic or alkaline fluids at low temperatures and low pressures; in particular, they have excellent shut-off capabilities. I would like to ask whether it can be used to regulate fluids?

Is the image you used the diaphragm control valve? Is this type of valve lining prone to high failure rates?
The failure rate is low in other aspects; it’s just that the diaphragm may need to be replaced every six months, as it is a wear-prone component.
Already every six months this quickly? Can an ordinary instrument technician replace the diaphragm?
How long can rubber-lined and fluorine-lined versions be used respectively?
It’s easy to replace; any ordinary mechanic can do it.
I’m talking about the possibility; of course, it depends on the operating conditions, so it’s impossible to give a specific time.
Based on your experience of using it? Fluorinated linings have a long service life, right?
Yes, those lined with fluoropolymer are more durable than those lined with rubber; of course, their price is also much higher
