The Midland Haldex AL430668 is a Full-Function ABS (FFABS) valve designed for trailer ABS modulator systems. This patented FFABS valve integrates spring brake control in a single unit, simplifying plumbing and reducing failure points at the valve block. Port layout: one 3/8" supply port with integral filter, one 3/8" control port, four 3/8" delivery ports, four 3/8" spring brake ports, and a 1/2" / 3/4" swivel nipple reservoir port with lock-nut for tool-free serviceability. Crack pressure is rated at 4.0 PSI; operating voltage is 12V. Filters are standard in both the control and supply ports. The production part number is embossed on a metal tag for positive ID in the field. Note that the ECU and bracket may need to be transferred from the existing valve during installation.
