Lift Axle Valve
Bendix

The lift axle valve is a compact, electrically actuated solenoid device designed to control auxiliary axle height for trailers and tractor-trailer configurations. A mounting-hole diameter of 0.33 inches facilitates secure installation to compatible brackets in the chassis or mounting plate assemblies. The valve operates on 12-volt systems, aligning with standard vehicle electrical architectures for auxiliary lift mechanisms. Its maximum operating pressure of 145 psi supports reliable actuation of air-lines and lift cylinders under typical fleet loading scenarios, while a wide operating temperature range of -40 to +176 degrees Fahrenheit ensures dependable operation across winter and summer conditions. This component is integral to vehicle stability and weight distribution strategies, enabling efficient load transfer and tire-wearing patterns while preserving ground clearance and traction under varying road grades. VMRS 013-018-026 provides the repair and maintenance coding for service documentation, with category context indicating its role within the lift-axle subsystem of heavy-duty tractors and trailers.
