What are the type testing procedures and standards for ball valves? What diameter ranges and pressure classes are covered? Feel free to discuss

For valves, the diameter is usually 2*DN; for example, if the valve you provide for testing is DN250, then the diameter range can go up to DN500. 4. Regarding pressure, the options are 16 MPa, 35 MPa, and 42 MPa. 5. Of course, the specific details can be found in the table specified in standard TSG D7002; different products have corresponding pressure ranges.
