Features & Benefits

  • Three 3/8-inch NPT ports provide connection points for air suspension systems, height control valves, and dash controls
  • Allows on-demand activation or deactivation of lift axles without manual intervention at the axle itself
  • Extends tire lifespan by limiting unnecessary contact between auxiliary axles and the road
  • Compact form factor supports frame rail or crossmember mounting with minimal footprint

Sealco Lift Axle Control Valve

The Sealco Lift Axle Control Valve is known to regulate air pressure between the suspension and lift mechanisms. With standard 3/8-inch NPT ports, this valve serves as the interface between driver inputs and axle behavior, directing when lift axles are deployed or retracted in response to road conditions or load requirements. This functionality is commonly installed in trailers and multi-axle tractors that need to adapt axle positioning dynamically during transport. The Sealco 110591 also contributes to better weight distribution and fuel usage by reducing tire drag when the extra axle is not needed.
