Self-acting control valve
Thread Content
Gentlemen! Who knows how to adjust this self-acting control valve? It would be great if a schematic diagram of its principle and structure could be provided. Thank you!
Adjust the locking nut at the top; once that’s done, you can adjust the one below
To check the structure or operating instructions, there are those for pressure before controlled logging and those for pressure after it.
Once the hex nut at the top is loosened, the hex bolt at the top is used to adjust the pressure upward or downward.
It looks very familiar; it seems to be the same as the valve at the outlet of our fire department’s pressure stabilizing pump. This type of valve actually serves a pressure stabilizing function. After we set it to 1MP, it stopped moving. Generally, the general contractor adjusts it all last time. Unless it becomes unstable after making the change, then adjust it. It’s adjusted at the part where the cap is adjusted
The screw at the top can be adjusted; generally, turning it clockwise increases the voltage while turning it counter-clockwise decreases it
