Standardization entails manufacturing each component in conformity with the approved CAD drawing provided by the customer, which must, of course, comply with all applicable standards, including those for valve casting manufacturers, shell tests, face-to-face dimensions, leakage classes, connection dimensions, etc. Use the MSS, API, ASME, BS, DIN, GB, and JB standards as references.
For industrial valve casting manufacturers made of raw materials, different grades of steel castings bodies, forging bodies, special alloy steel, and duplex steel material must be taken into account.
