New, Hydraforce. A screw-in, cartridge-style, spool-type flow divider/combiner. Optional flow dividing/combining ratios are maintained regardless of system operating pressure conditions. In the dividing mode, the FD10-40 will divert input flow from port 3 to ports 2 and 4 based on the ratio specified, regardless of operating pressure. The cartridge will combine input flows from ports 2 and 4. Should circuit operation result in a blockage of either 2 or 4, the opposite port may also close under certain conditions. Should this potential exist, consult the factory.
