Looking to source a flow control valve for a dancing fountain I'd like to build in my backyard. I'm hoping to find something common andcheap from old automobiles. Though, I need linear control...not sure if that exists in a relatively modern vehicle. My goal is just to charge a network of PVC with a 1000+ gph fountain pump and place these actuators right between the fountain heads and the network. My plan was to interface something from controlanything.com between a midi controller and the actuators. My fear is that the speed of the actuator will cost me...as I need to time the actuator movements to music. Any tips would be much appreciated.
