Which type of flow-regulating valve has a lower pressure drop at the same flow rate?

It is also used for flow control or pressure regulation at the distribution station. As far as I know, they are: 1. Cage-type stop valves (imported ET series produced by Fisher, and the LT9B41Y type made in China by Sichuan Changyi); 2. Cage-type axial flow valves (imported RZD series from Mokveld, and domestic models such as Teris PL4200 and Tianjin Betel Valves PCV-A800); 3. V-type ball valves (made in China by Zigong Zigao Valves, etc.)
