Μέθοδος σύνταξης για αμερικανικά πρότυπα μοντέλα βαλβίδων
The valve industry has entered a period of global development today; The types and materials of American standard valve models are increasing, and the compilation of valve models is becoming increasingly complex; The standardization of American standard valve models provides convenience for the design, selection, and distribution of βαλβίδες; The American standard valve model should usually indicate seven elements: American standard valve type, American standard valve driving method, American standard valve connection form, American standard valve structural characteristics, American standard valve nominal pressure, American standard valve sealing surface material, and American standard valve body material.
There is no standard specification for American standard valve models domestically or internationally, and major design institutes, engineering companies, and large valve enterprises have their own set of American standard valve model representation methods.
The following are common methods for preparing American standard valve models:

Note: The material of gasket, bolt and nut for each valve is determined by “valve body material”.
For valves with three levels of CL900.1500.2500, pressure sealed valve covers are generally used, and the “valve cover gasket” and “valve cover bolt” items default at this time.
