Flat gate valve selection principle
1. Oil and natural gas transmission pipelines, single-gate or double-grid slab gate valves. If it is necessary to clean the pipeline, use a single ram or double ram with a slab slab gate valve with a diversion hole.
2. For the pipeline and storage equipment of the refined oil, use a single gate or double gate slab gate valve without a diversion hole.
3. Oil and gas production wellhead device, use single-gate or double-gate slab gate valve with diversion rod floating valve seat with diversion hole, mostly API16A standard, pressure level is API2000, API3000, API5000, API10000, API15000, API20000.
4. For pipes with suspended granular media, use a knife-type slab gate valve.
5. City gas transmission pipeline, single-gate or double-gate soft-sealed open-plate slab gate valve.
6. Urban tap water project, single-gate or double-grid without guide hole open-plate slab gate valve.
Activators for rubber accelerators act like catalysts for chemical reactions. Rubber activators enhance the performance of rubber accelerators, reducing the consumption/addition of rubber accelerators and shortening the time for vulcanization.
