Key Sealco 110415 Service Relay - 4 Port, 4.0PSI

The Sealco 110415 is a high‑quality, four‑port service relay valve engineered for heavy‑duty air brake systems - especially on tandem axle trailers with four brake chambers. Designed to help efficiently distribute service brake air pressure, this valve enhances brake responsiveness and ensures balanced performance across all connected brake chambers.

 

Key Features & Benefits

  • Four Delivery Ports: Provides air to up to four brake chambers simultaneously, ideal for multi‑axle trailer service brake applications.
  • Nominal Crack Pressure - 4.0 PSI: Activates reliably once control pressure reaches around 4 PSI, helping reduce lag in brake actuation.
  • Nipple Mounted: Designed for straightforward installation using standard 6003/6006 nipples (mounting hardware sold separately).
  • Built for Durability: Constructed to withstand the harsh environment and frequent cycling typical in commercial transport.

 

Applications

The Sealco 110415 service relay valve is typically used in non‑ABS trailer air brake systems where multiple brake chambers must be actuated from a common service control line. Its four outlet design makes it especially suitable for tandem axle trailers and heavy‑load applications requiring reliable air distribution.
