Closed or open valve cap, as the name suggests, is to see whether the bonnet is sealed, and wrench is not too much, there are wrenches can also be closed valve cap, but also is an open valve cap.The above is my personal explanation, if you want to further understand, you can refer to the relevant standards of API520. Or find some safety valve samples, which will be described in detail.
