What It Does:

The 3-44 Spring is part of the internal operating mechanism of the PK Lindsay medium mixing valve. It works with the spindle and related components to provide proper movement and operation as abrasive flow is adjusted.

Over time, repeated cycling, abrasive contamination, and corrosion can cause a spring to weaken, distort, or break. Replacing a worn spring during a mixing valve rebuild can help restore smooth and dependable adjustment.

Common Signs the Mixing Valve May Need Service:

• Mixing valve is difficult to adjust
• Adjustment does not operate smoothly
• Valve does not maintain the desired setting
• Spring is broken, corroded, or distorted
• Inconsistent abrasive delivery
• Internal valve components show excessive wear
