Are you looking for an alternative for your Flow Divider circuit that will address the issues of multiple division, irregular percentage splits, adjustable ratios, inlet flow variance versus accuracy and pressure drop? If so, an alternative works for dividing pump flow only. If you need combining too, you might have to stick with the traditional flow divider / combiner (or read next week’s article to see a combining solution).
Flow dividing circuits are used in many mobile applications to make full use of a varying input flow. Spool type dividers can be integrated into manifolds and are available in many sizes and fixed ratios. Although they can be cascaded, they are individually limited to a 2-way split. The valve ratios (i.e. 50/50 or 20/80) are fixed and factory preset by varying each spools flow specifications.
