Praher E-50-S2 Multiport Valve Top Assembly (Key Hub/Lid) – 2" – White – Includes O-Ring & Position Decal

The Praher E-50-S2 is a replacement top assembly (key hub / lid) for compatible 2" Praher ABS top-mount and side-mount multiport valves used on pool and spa sand filters. This assembly includes the lid/top housing, the handle/key hub components, an O-ring seal, and a position decal that shows valve settings (Filter, Backwash, Rinse, Waste, Recirculate, Closed, etc., depending on your valve model).

Key Features

  • Part Number: E-50-S2
  • Type: Multiport valve top assembly / key hub / lid assembly
  • Valve Size: 2"
  • Color: White
  • Includes: O-ring seal and position decal/label
  • Use: Restores proper multiport operation and sealing on compatible Praher-manufactured valves

Common Applications

  • 2" Praher ABS top-mount and side-mount multiport valves on sand filters
  • Replacement top for many private-label valves manufactured by Praher (varies by brand/model)

Common Reasons to Replace

  • Cracked or warped lid/top that won’t seal properly
  • Handle/key hub is worn, loose, or difficult to operate
  • Persistent leaking around the lid O-ring area
  • Decal is missing/faded and valve positions are no longer readable

Compatibility Notes

  • This part is intended for 2" Praher ABS multiport valves. Confirm your valve is the 2" version before ordering.
  • Multiport tops can look similar across brands—best practice is to match your existing part number or confirm by your valve model.
  • This is the top/key hub assembly only (not the full multiport valve body).

Replaces / Cross References

  • 4600-1152 (common catalog cross reference)
  • May also be listed under additional distributor/vendor numbers depending on the supplier

Installation & Maintenance Tips

  • Always shut the pump off and relieve filter pressure before opening a multiport valve.
  • Clean the lid O-ring groove and the mating surface before reassembly. Dirt and sand can cause leaks and premature O-ring wear.
  • Lightly lubricate the O-ring with silicone pool lube (do not use petroleum-based grease).
  • If the valve handle feels rough or positions don’t “index” cleanly, inspect/replace the spider gasket and internal sealing surfaces as needed.
  • Never change multiport positions while the pump is running—this can damage the gasket and internal components.
