retro fitting superflow 901 ok! ready to do this, need help please
would this be powerful enough?
This high torque and precision bipolar Nema 17 stepper motor with 0.9° step angle (400 steps/revolution). Each phase draws current 2A, allowing for a holding torque of 46Ncm(65.1oz.in).

would 3nm be enough torque to operate the water brake valve? cheers
Yes 425oz.In/3Nm stepper motor is ample
Sounds good. The Land & Sea valve is just 55 steps from fully open to fully closed, and it works surprisingly good. It hunts between steps a little in steady state, but RPM control is very good.
But your idea of 400 steps should work good too. Otherwise you can try the micro stepping option, which most controllers support.
