Repair Kit Application
The B5116-RKS400 is designed to replace the silicone seat in compatible 4" Dixon B5116-Series butterfly valves.
The valve seat is the elastomer component that seals around the butterfly disc when the valve is closed. Replacing a worn, damaged, or deteriorated seat can restore sealing performance while allowing the existing valve body and other reusable components to remain in service.
This repair kit contains the replacement seat only and should not be confused with a complete butterfly valve assembly.
Silicone Seat Construction
B5116-RKS400 uses a silicone elastomer seat designed for compatible sanitary process applications.
Silicone is commonly used in hygienic processing systems where flexibility, cleanliness, and compatibility with suitable process conditions are important.
Always confirm silicone compatibility with the actual product, cleaning chemicals, sanitation procedures, operating temperature, pressure, and other process conditions before installation.

Repair Kit Selection
Before ordering B5116-RKS400, confirm that the existing valve is a compatible 4" Dixon B5116-Series butterfly valve and that silicone is the required seat material.
Dixon uses different repair kit part numbers according to valve size and elastomer material. B5116-RKS400 is specifically identified as the 4" silicone replacement seat.
If the valve requires an EPDM seat instead, B5116-RKE400 is the corresponding 4" EPDM repair kit.
Inspection & Replacement
Before servicing the butterfly valve, isolate the process line and confirm that the system has been safely depressurized, drained, cleaned, and brought to a safe temperature according to applicable facility procedures.
Disassemble the valve according to applicable Dixon service procedures and inspect the existing seat, butterfly disc, valve body, stem, and other internal components for wear, damage, contamination, or chemical deterioration.
Install the replacement silicone seat in the correct orientation without cutting, twisting, stretching, or otherwise damaging the elastomer.
Inspect the butterfly disc and sealing surfaces before reassembly. Components with scratches, deformation, corrosion, or other damage that could affect sealing performance should be evaluated before the valve is returned to service.
After reassembly, cycle the valve through its operating range and verify proper operation and leak-free performance under appropriate process conditions before returning the system to normal service.
