Last time we discussed how to make a flow divider with separate cartridges. If this was of interest the following goes a little deeper into this subject and shows how to maximize the versatility and address general flow divider issues.First off, it’s worth noting that unlike Flow Sharing the pump itself does not have to be load sensed if all flow is to be utilized in a stand-alone circuit. a) |

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.
