Application & Fitment
The swing lever mounts on the S-valve shaft and is driven by the plunger/swing cylinder to rotate the S-tube between hopper and delivery side. Worn or rounded 25-tooth splines can cause S-valve play, wear plate leakage and poor switching performance. Before ordering, please confirm DN80/Q80 size, 25-tooth spline, shaft diameter, mounting hole pattern and cylinder connection against your Putzmeister equipment manual or existing part.
When to Replace
S-valve switching is slow, unstable or incomplete
Clearance/play between swing lever and S-valve shaft
25-tooth spline is rounded, chipped or worn
Abnormal noise from S-valve swing mechanism
