I just want to confirm the auxiliary close function

It is indeed a function to help keep things tight, in order to prevent valve position fluctuations. Experience has shown that it doesn’t matter much if some valves lack this feature; after all, it’s better to be cautious just in case.

It can improve the control accuracy of the valve. There is a gap between the valve feedback rod and the actuator feedback rod; a spring is used to eliminate this gap, thereby reducing the adjustment dead zone of the actuator and improving the control accuracy of the valve!
