Valve model numbers typically indicate valve type, actuation method, connection type, structural features, sealing surface material, valve body material, and nominal pressure. Standardization of valve model numbers facilitates valve design, selection, and sales.
Today, the types and materials of valves are increasingly diverse, making valve model numbering more complex. Although my country has a unified standard for valve model numbering, it is increasingly unable to meet the needs of the valve industry's development. Valve manufacturers generally use a unified numbering method; where a unified numbering method cannot be adopted, each manufacturer develops its own numbering method according to its needs.
The "Valve Model Numbering Method" applies to gate valves, throttle valves, ball valves, butterfly valves, diaphragm valves, piston valves, plug valves, check valves, safety valves, pressure reducing valves, and steam traps for industrial pipelines. It includes valve model numbering and valve naming.
