The check valve designed, manufactured, produced and tested according to the American standard is called the American standard check valve, so what is the standard size of the American standard check valve? What is the difference between it and the national standard check valve? At present, the standard size of American standard check valves is more popular to be designed and produced in accordance with API and ASME standards, and many American standard valve standards are actually common in the world. The standard dimensions of American Standard check valves are as follows: Design standards: API 6D, ASME B16.34, API 594, BS 1868, GB/T 12235, GB/T 12236, JB/T 8937 Structure length: ASME B16.10, API 6D, GB/T 12221 Connection standards: ASME B16.5, ASME B16.47, ASME B16.25, GB/T 9113, JB/T 79, HG/ T 20592 Pressure test: API 598, API 6D, GB/T 13927, GB/T 26480 Pressure and temperature rating: ASME B16.34, GB/T 12224 The use of American standard globe valves in high-pressure environments The main differences between American standard check valves and national standard check valves are as follows: 1. The unit of nominal diameter is different; 2. The flange mark is different; 3. The length of the structure is different; 4. The inspection requirements are different.
