Made an update to my water control valve for my GoPower 512 water brake.  I originally put this 1.5" globe valve in with a stepper motor.  As you can see there is a large flat valve disc which once cracked open provides a bunch of water to the brake and kind of hard to control the load when starting to take water away.

I made this new cone shaped valve with hopes that it makes the low opening flow a little more controllable.  Just sharing for everyone's information.

Thanks
