The principle of selection of flat gate valve
1. For oil and natural gas pipelines, use flat gate valves with single or double gates. If you need to clean the pipeline, use single or double gate open-rod flat gate valve with diversion holes.
2. For the transportation pipeline and storage equipment of refined oil, use single gate or double gate flat gate valve without diversion hole.
3. For oil and natural gas mining wellhead devices, single-gate or double-gate flat gate valves with dark rod floating valve seats and diversion holes are used, most of which are API16A standards, and the pressure levels are API2000, API3000, API5000, API10000, API15000, API20000.
4. For pipelines with suspended particulate media, use knife-shaped plate gate valves.
5. For the city gas pipeline, use single gate or double gate soft-seal open-rod flat gate valve.
6. For urban tap water projects, use single or double gate open-rod flat gate valves without diversion holes.
