Adjustable Proportional Valve

Part# AL148

This part is used to "equalize" the lift axle in terms of weight to meet provincial regulations. Ontario's SPIF regulations are an example of this.


In most cases, the lift axle and fixed axles do not have the exact same weight vs. pressure curve. This valve allows the installer to adjust the ratio between the lift axle and the fixed axles to balance the weight correctly.
