What It Does:

The 7-03CS Bolt with Stop is part of the mechanical adjustment system of the PK Lindsay large mixing valve. It works with the spindle arm and related components to control movement of the valve adjustment mechanism.

The stop helps limit movement of the mechanism, allowing the mixing valve to operate within its intended adjustment range.

Years of repeated adjustment, corrosion, or mechanical wear can damage the bolt, threads, or stop. A worn or damaged component can introduce excessive movement or interfere with proper abrasive flow adjustment.

Common Reasons for Replacement:

• Bolt is bent or physically damaged
• Stop is worn or damaged
• Threads are stripped or deteriorated
• Excessive corrosion
• Adjustment mechanism has excessive movement
• Bolt is seized or difficult to operate
• Original bolt is missing from an incomplete valve assembly
• Rebuilding an existing large mixing valve

Important When Rebuilding the Valve

The 7-03CS Cover Bolt with Stop – Diagram Item #15 is not included in the PK Lindsay 7-36A Large Mixing Valve Rebuild Kit.

If you're rebuilding the valve with the 7-36A kit, inspect the existing bolt and stop and replace it separately if worn, damaged, or missing.
