Item # R431003743, Aventics "A" Pilotair® Cartridge Repair Kits





"A" Pilotair® Cartridge Repair Kits
  • Simplified Repair
  • Factory Tested
  • Fits Most Previous Design "A" Pilotair Valves
  • Corrosion Resistant
The one piece valve cartridge replaces the individual valve parts assembly for the following devices:

"A" PILOTAIR Valves
"H" CONTROLAIR Valves
FLEXAIR Valves - Side Valve Cavity

Quick, positive repair and conversion can be accomplished by directly replacing the old individual parts with the new factory pressure tested cartridge. The cartridge valve simplifies repair and eliminates possible problems due to improper parts assembly. The modern engineered plastic and stainless steel construction provide superior corrosion resistance and sealing characteristics.

NOTE:

With the above kits, the elastomer seals and some common wear parts in the valve portions of the assemblies can be repaired. On severely worn or damaged valves, additional parts may be required.

The above kits do not contain any parts for the mechanical operating portions of the valves. The mechanical operating portions of the valve should be repaired when necessary, with individually selected parts, and tested before being put in service.

Refer to Service Bulletin SM-700.7400 for additional parts information and service instructions on the type "A" PILOTAIR pneumatic directional valves.
