What components need to be replaced at the beginning of valve use and after long-term use?
Thread Content
I’m seeking advice from fellow users: what types of components are likely to develop **minor issues** that require repair or replacement, either at the beginning of using a valve or after it has been in use for an extended period of time? Thank you to all the fellow travelers for their help:hug::lol
The valve core and valve seat need to be repaired, and the packing needs to be replaced.
For ball valves, it is generally necessary to replace the valve seat, that is, the sealing ring and packing. If the ball surface is worn, it needs to be reworked; if it cannot be reworked, it must be replaced with a new one. For butterfly valves, the seat or disc needs to be replaced. For gate valves, check the gate; for globe valves, it is usually the valve seat and valve stem that are most prone to damage. There are too many valve models to list here; for more information, please communicate via private message. 412372706
Wear and scratches on the valve core (disc). Wear and scratches on the seal. Wear of the valve stem packing. Corrosion, fracture, detachment, and twisting of the valve stem connector.
Disk valves are all used to regulate flow rate
