Change In The Vane Angle In Vertical Roller Mills

A change in rocker shaft height in addition to the tip contact centering changes caused by any valvetorocker pad angle 10 degrees in the tfs3 heads i measured also causes the rocker to angle either up or angle down any angle increase from right angles also moves the valve tip closer to the shaft it shortens the reach of the rocker tip.
