What is the maximum diameter of a V-shaped ball?

What is the maximum diameter of a V-type ball valve? A control loop requires a DN400 V-type control valve – is it possible to manufacture one? It’s from that manufacturer – what’s the price? Everyone, please give some advice!
1. Regarding regulating ball valves, there is no fixed specification for the maximum diameter. If a V-type valve must be used, it is recommended that you consult some well-known brands such as Shanghai Nailais, Wuxi Gongzhuang, Wuzhong Instrument, Yamatake Gongzhuang, and Shenzhen Wanxun; the prices for these valves will certainly be very high. 2. Some of my views: What are the conditions regarding the operating parameters? Medium? Pressure? Temperature? Viscosity? Corrosion? For a diameter of 400, butterfly valves should be given priority for two reasons: first, they are more cost-effective and easier to install; second, they can meet the requirements regarding leakage levels and opening degrees. The above are purely personal opinions for reference only, hehe
Disc valves generally cannot be used in control circuits, whereas V-ball valves possess control characteristics, either linear or logarithmic; they are therefore \"control\" valves； Disc valves are only used when the pipe diameter is relatively large
Reply to 3# ROSEHOOD: Theoretically, both butterfly valves and V-ball valves can be used for regulation purposes. V-ball valves exhibit approximately equal percentage characteristics, but in practical terms, the regulation performance of both types is not ideal. Given this, why not choose the butterfly valve, which offers a better cost-performance ratio? Hehe
It seems the maximum is 14\" (350).
A larger diameter means greater leakage and higher costs. For large diameters, it’s better to choose a butterfly valve! The KZ5000 http://www.wellkey.cn series of multi-layer sealed butterfly valves can meet your requirements.
