V-ball valve and global ball valve
Thread Content
Who can explain in detail the differences between V-ball valves and regular ball valves in terms of usage? What are the considerations for selection?
O-type ball valves are generally used as shut-off valves, while V-ball valves are typically used in control valves
The flow-through surface of a V-type ball valve is V-shaped. A standard ball valve not only has a circular flow surface but also features a valve disc that is essentially a complete sphere (global ball valve). In V-type ball valves, in order to ensure that the flow characteristics are not affected by areas other than the flow surface of the valve disc, the spherical shape of the valve disc is greatly reduced; without paying close attention, it’s impossible to tell that it is actually a ball. The flow characteristics of ordinary ball valves are basically those of quick opening ； Depending on the shape of the notch, V-type ball valves can have various flow characteristics as required.
Is there a saying that V-balls are more suitable when using particle-type materials for sampling?
Haven’t heard of it. But it is feasible to release the larger particles one by one using a V-type ball valve.
The flow characteristic of V-ball valves is equal percentage, while O-valves open quickly; therefore, V-valves are generally used as control valves, and O-valves are used as on/off valves
