What It Does:

The small mixing valve regulates the amount of abrasive media introduced into the compressed air stream. The C-4X spindle arm is part of the valve's adjustment mechanism, working with the spindle and related components to control the mixing valve position and abrasive flow.

Years of use, repeated adjustment, corrosion, or mechanical wear can eventually damage the spindle arm or create excessive play in the adjustment mechanism.

Replacing a worn or damaged spindle arm can help restore smooth, dependable adjustment without replacing the complete mixing valve.

Common Signs the Spindle Arm May Need Replacement:

• Mixing valve is difficult to adjust
• Excessive play in the adjustment mechanism
• Valve will not maintain the desired setting
• Bent or damaged spindle arm
• Worn connection points
• Inconsistent abrasive adjustment
