Valve Model Preparation

Preface to the preparation of valve models

The valve model should usually indicate the valve type, drive mode, connection form, structural characteristics, sealing surface material, valve body material and nominal pressure. The standardization of valve models provides convenience for valve design, selection and sales. Nowadays, there are more and more types and materials of valves, and the model preparation of valves is becoming more and more complex. Although China has a unified standard for valve model compilation, it is increasingly unable to meet the needs of the development of the valve industry. For new valves that cannot use standard numbers, each manufacturer can prepare models according to their own needs.

The "Valve Model Preparation Method" standard is applicable to gate valves, throttle valves, ball valves, butterfly valves, diaphragm valves, plunger valves, plug valves, check valves, safety valves, pressure reducing valves, steam traps, etc. for industrial pipelines. It includes valve model compilation and valve naming.
