Selection Principles Of Flat Gate Valves
1. For oil and natural gas pipelines, use Lined Gate Valve with single or double gates. If the pipeline needs to be cleaned, use a single or double gate with a guide hole and a rising stem flat gate valve.
2. For finished oil pipelines and storage equipment, use a single or double gate without a guide hole.
3. For oil and natural gas wellhead devices, use a single or double gate with a non-rising stem floating seat and a guide hole. Most of them are API16A standard, and the pressure levels are API2000, API3000, API5000, API10000, API15000, API20000.
4. For pipelines with suspended particle media, use a knife-type flat gate valve.
5. For city gas pipelines, use a single or double gate with a soft seal rising stem flat gate valve.
6. For urban tap water projects, choose single-disc or double-disc open-stem flat gate valves without guide holes.
