Flow Control Valve
Flow Divider / Combiner, Heavy Duty, Multi-Function

QFD10-41  = Minute Flow/ Collection Flow Valve, Oil Cylinder synchronization =



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 QFD10-41 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. The QFD10-41 is designed to allow synchronizing flow to the opposite cylinder once a cylinder has “bottomed” in the combining mode..
