What It Does:

The 3-44 Spring is part of the internal adjustment mechanism of the PK Lindsay large mixing valve. It works with the spindle and related components to maintain proper tension and movement within the valve assembly.

After years of service, a spring can weaken, corrode, break, or lose its original tension. This can affect the movement of the internal valve components and make consistent abrasive adjustment more difficult.

Replacing a worn or damaged spring during mixing valve service can help restore proper mechanical operation without replacing the complete valve assembly.

Common Reasons for Replacement:

• Spring is broken or damaged
• Spring has become weak or fatigued
• Excessive corrosion or deterioration
• Spring no longer provides proper tension
• Mixing valve adjustment is not operating smoothly
• Original spring is missing during disassembly
• Performing a complete large mixing valve rebuild

Also Included in the 7-36A Rebuild Kit

The 3-44 Large Mixing Valve Spring – Diagram Item #9 is also included in the PK Lindsay 7-36A Large Mixing Valve Rebuild Kit.

If the spring and several other internal components are showing wear, the complete 7-36A rebuild kit may be more economical than purchasing the individual parts separately.
