FAQ
-
Q: What are some common malfunctions? How can I troubleshoot them myself?
A:
① Outlet pressure cannot be adjusted: Check if the inlet pressure is sufficient; check if the adjusting spring is damaged; check if the valve core or diaphragm is stuck.
② Outlet pressure continues to rise: The main valve core may be stuck by foreign objects and unable to reset, or the valve seat seal may be damaged, requiring cleaning or replacement.
③ Air leakage: Check if the threaded seals at the interface are intact, or if internal seals such as the diaphragm are aged or cracked.
④ Insufficient flow: Check if the filter element is clogged, or if there is throttling in the pipeline or interface.
