LOAD VALVE

I have made a linear valve from a globe valve by modifying the valve disc.

Considering the relationship between flow rate and cross-sectional area (Formula Q=AV), the curve profile of the new valve disc was drawn in CAD by finding the equation of the curve and then getting it manufactured by a CNC lathe. 

Found to be a cost-effective alternative to using the L&S and is working well with my setup.

Attached is a photo of the initial valve disc and the new disc.

@nsmve That is the exact valve that I am using and the same stepper motor.  I still haven't dug mine back out of the corner to test the new speed sensor setup.  Between Christmas and New Year's I should have some time to do so.  Looking forward to see how your's works for you.

Thanks for the info and pictures, that looks like a realy simple solution.

Do you know how many turns the valve is open to closed ? I wasn't sure the respose time would be quick enough with the stepper directly coupled to the valve

Regards

@swmotorsport my friend this valve have 9 turns ..response is good quick and hard torque steeper motor is more than enough for a water brake
