Excuse me, diaphragm valve
Thread Content
What is the typical leakage level that diaphragm valves can achieve as automatically controlled shut-off valves, and what is the highest leakage level they are capable of achieving?
The highest level of leakage can be achieved, but the pressure is not very high, at only 0.6–1.0 MPA
I’m asking what level can be reached; the answer from above is completely off-topic
It can reach level VI or H. Can you understand that?
When responding upstairs, please pay attention to the question – you only answered half of it. I also asked what level of performance general diaphragm valves can achieve; as far as I know, it’s generally grade IV, with the highest being grade VI. I just wanted to hear what others have to say.
At a glance, I can tell you’re an expert; you even managed to invent the idea that V level is the highest level, haha
Those up there, think carefully before speaking – is it reasonable to give such answers and still expect rewards?
The original poster’s way of asking questions seems rather arrogant, which is uncomfortable to read
Let me tell you: the American standard divides leakage levels into five categories, II, III, IV, V, and VI, with water, air, and nitrogen being used as the testing media. The Chinese standard, on the other hand, has eight leakage grades, labeled A, B, C, D, E, F, G, and H; the testing media include air and nitrogen at temperatures of 10–50 degrees, as well as water and kerosene. The number of bubbles released is measured under conditions where a tube with an outer diameter of 6 MM and a wall thickness of 1 MM is inserted vertically into water at a depth of 5–10 MM, with the surface of the tube end having to be smooth. Is this clear now? This post was last edited by QHDKD on 2007-9-20 at 16:52.]
I also humbly ask this expert to enlighten me: what exactly is Level H? I am ignorant and unlearned, and truly have no idea. I earnestly seek your guidance
For American standards, follow ANSI B16.104-1976
