I needed a forklift part and wasn’t sure which one fit. They asked for the model and serial number, got back to me quickly, and made sure I ordered the right one. Really helpful.

Product Overview

The Trailer Spring Brake Control Valve precisely regulates spring brake hold-off pressure at 55 PSI for heavy-duty trailer air brake systems. Designed as a direct replacement for Sealco 110800 valves, this trailer spring brake control valve ensures consistent brake release and reliable parking brake function. Fleet operators and owner-operators rely on the valve to maintain safe and predictable trailer braking.

Key Features & Performance

  • Pre-set 55 PSI pressure output matches OEM specification for spring brake hold-off
  • Direct replacement form factor simplifies installation on existing Sealco 110800 mounts
  • Corrosion-resistant housing and seals extend service life in harsh under-trailer environments
  • Consistent crack pressure and flow characteristics prevent brake drag or premature engagement
  • Enhanced internal design reduces sticking and improves cold-weather reliability

Common Uses

  • Trailer spring brake control circuits on commercial dry vans and flatbeds
  • Heavy-duty air brake systems on agricultural and construction trailers
  • Replacement of a worn or leaking Sealco 110800 valve in fleet preventive maintenance
  • Ensuring parking brake hold-off pressure remains stable during extended stops

Technical Specifications

  • Part Number(s): 110800
  • Operating Pressure: 55 PSI

Frequently Asked Questions

Q: Can this valve be used with other brands besides Sealco? A: It is engineered as a direct-fit replacement for Sealco 110800 valves and may function with other 55 PSI spring brake circuits if port configuration and mounting match.

Q: Is the pressure setting adjustable? A: This Trailer Spring Brake Control Valve is factory-set to 55 PSI and is not field-adjustable to preserve consistent brake system performance.
