Installation and usage precautions
1. All types of safety valves should be installed vertically.
2. The outlet of the safety valve should be unobstructed to avoid pressure.
3. Before installation, safety valves should be specifically tested and their sealing properties checked.
4. Regular inspections should be conducted on safety valves in use
