Problems with stand-alone differential pressure valves
Thread Content
Two reports are required: one for the static balance valve and one for the self-acting differential pressure valve. The differential pressure at the outlet of the self-acting differential pressure valve should be set at 45–50 KPA, while the differential pressure in the branch pipes should be 100 KPA. Is there a detailed explanation of the principle of self-acting differential pressure valves? Regarding the debugging reports mentioned above, is the first one related to use with a static balance valve, and the second one for use alone?
A self-acting control valve should be part of a valve assembly in terms of process configuration; it can be found by searching on Baidu.
