What It Does:

The 800-001 Cushion is an internal component of the PK Lindsay large mixing valve assembly. It works with the other valve components to help maintain proper positioning and operation of the abrasive metering mechanism.

The inside of a mixing valve is subjected to a particularly harsh environment. Abrasive media, repeated valve movement, and normal mechanical wear can gradually deteriorate the cushion and related internal components.

Replacing a worn cushion during valve service can help restore proper operation and extend the usable life of the existing large mixing valve.

Common Reasons for Replacement:

• Cushion is worn or deteriorated
• Visible abrasive wear
• Cushion is cracked, distorted, or damaged
• Mixing valve adjustment has become inconsistent
• Existing cushion is missing
• Valve is being disassembled for repair
• Performing a complete large mixing valve rebuild

Also Included in the 7-36A Rebuild Kit

The 800-001 Cushion – Diagram Item #4 is also included in the PK Lindsay 7-36A Large Mixing Valve Rebuild Kit.

The 7-36A kit includes two Item #4 cushions, along with the other primary internal wear components needed to rebuild the large mixing valve.

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

Finding Parts for Older PK Lindsay Equipment

PK Lindsay blast machines may no longer be manufactured, but many 300LA and 600LA machines remain in service. Individual large mixing valve components can be difficult to identify and locate when you're working from an older exploded parts diagram.

That's why we include the original PK Lindsay part number and exploded diagram item number whenever possible—so you can identify exactly what you need before ordering.
