What's the difference between a double valve and a single valve in a Nepal electric pressure cooker?

Simply answer, Nepal's double valve is able to control two kinds of pressure, while the single valve can only control a kind of pressure, a chestnut: do a fish soup, may need a very small pressure is enough, but the stew a beef, it needs a larger pressure, so the double valve control is very simple, directly through the pressure of a paragraph and the second pressure to realize it. But the single valve can only be realized through the gap heating not let the pressure is too high, taste and so on, of course, dual-valve is even better. The actual Nike Air Max 90 is actually a very good choice for the actual Nike Air Max 90, as well as the Nike Air Max 90 is actually a very good choice for the actual Nike Air Max 90, as well as the Nike Air Max 90 is actually a very good choice for the actual Nike Air Max 90. It can be said that Nepal's products are really genuine. The United States, Jiuyang and other manufacturers use silicone spool valve, such a product is just bought back when there is no problem, a long time, and then the product of high temperature and high pressure, silicone aging, an aging valve began to leak, of course, the spool will be broken, the service life is not long. I hope to help you understand.
