What It Does:

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

Over time, a spring can weaken, corrode, become damaged, or lose tension. Replacing a worn spring during a mixing valve rebuild can help restore smooth and dependable operation.

Common Signs the Mixing Valve May Need Service:

• Mixing valve is difficult to adjust
• Adjustment does not operate smoothly
• Valve does not maintain proper adjustment
• Spring is broken, corroded, or distorted
• Inconsistent abrasive flow
• Internal valve components show excessive wear
