| I love my pwm valves have no experience with the hyd servo...my fertilizer dealer usees all john blue pumps and I was the first one around here to rig upa centrufugal pump with the pwm valve and a magnetic flow meter.
Its a suspension clay based complete blend we use down here and had some help from here putting it together and now the whole company is looking at this setup for the farmers with rate controllers wanting to control it better. The pump and valve is cheaper for them to purchase then a major repair on a john blue pump.
