Combining Cartridge Valves to Create a Versatile Flow Divider

Posted by David Price on Thu, Mar 17, 2011 @ 14:03 PM

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.

Properly Sizing Load Sensing Cartridge Valves

Posted by David Price on Wed, Mar 09, 2011 @ 09:03 AM

I think everyone is familiar with the term “you can’t get blood from a stone.” This directly relates to the lack of system performance when under-sized sensing valves are used in a load sensing circuit. Several times a year we receive calls from people stating that they can’t seem to get the required or anticipated flow out of a valve or a particular leg of their circuit.
