Safety valves are generally divided into two categories: full-opening type and slightly-opening type. The full-opening type is further divided into A22\A28\A42\A48\A62\A37. . . . . . Slightly open types are divided into: A21\A31\41\A27\A47. . . . . Could some expert who is familiar with this area provide a general overview of the safety valves available on the market?

I haven’t used that many types of safety valves. However, one can refer to HG/T 20570.2-95 regarding the installation and selection of safety valves.
