What It Does:

The 100-019 Washer is part of the internal assembly of the PK Lindsay small mixing valve. It works together with the cushion, spindle, spring, and other components that allow the valve to regulate abrasive media entering the compressed air stream.

Because these components operate in a harsh abrasive environment, normal wear can eventually affect valve adjustment and abrasive flow. Replacing worn components during a rebuild can help restore dependable operation.

Common Signs the Mixing Valve May Need Service:

• Abrasive flow is difficult to adjust
• Inconsistent abrasive delivery
• Excessive or insufficient abrasive flow
• Internal components show visible wear
• Mixing valve does not adjust smoothly
• Washer is worn, damaged, or missing during disassembly
