While efforts have been made to provide accurate details, inaccuracies may occur. It is advised to verify all information by contacting Sun Hydraulics directly.***
The Sun Hydraulics FSDCXAV (FSDCXAV) is a sliding spool, pressure-compensated flow divider designed to split oil flow into two separate branches within a hydraulic circuit at a specified ratio. This device is particularly suitable for applications involving unidirectional hydraulic motors and hydraulic cylinders where flow division is required in one direction only. It also serves multiple circuits from a single pump supply. The FSDCXAV model is physically interchangeable with other flow divider cartridges of the same frame size, maintaining consistent flow paths and cavity dimensions. Operating characteristics of this valve ensure that the circuit leg with the greatest load receives a higher percentage of flow when dividing. However, caution must be exercised in systems using rigid mechanisms to tie actuators together, as this can lead to cavitation or system lockup due to operating inaccuracies inherent in the valve design. In motor circuits with rigid frames or synchronized motion mechanisms, users may encounter cavitation, lockup, or pressure intensification. The FSDCXAV model features Sun's floating style construction to minimize internal binding due to excessive installation torque or machining variations. It has a capacity range of 1.5 to 8 gpm (6 to 30 L/min) and experiences a pressure drop of 30 psi (2 bar) at minimum rated input flow and up to 250 psi (18 bar) at maximum rated input flow. The valve has a hex size of 1-1/8 inches (28.6 mm) and requires an installation torque between 45 and 50 lbf-ft (61 to 68 Nm). Weighing approximately .55 lb (0.25 kg), it incorporates Viton seals for durability under various operating conditions. This model functions solely as a divider; reverse flow through the valve is not recommended as it may lead to operational issues below its minimum flow rating, where it behaves like a tee without dividing control until reaching sufficient flow levels.

Flow dividers are sliding-spool, pressure-compensated devices used to split oil flow to two different branches of a circuit in a designated ratio. These valves are suitable for applications that use the following: unidirectional hydraulic motors, hydraulic cylinders where flow division in one direction only is required, and multiple circuits that are serviced from one pump supply.

  • All flow divider and divider/combiner cartridges are physically interchangeable (i.e. same flow path, same cavity for a given frame size).
  • Operating characteristics cause the leg of the circuit with the greatest load to receive the higher percentage of flow in dividing mode. If a rigid mechanism is used to tie actuators together, the lead actuator may pull the lagging actuator and cause it to cavitate.
  • In applications involving rigid mechanisms between multiple actuators, operating inaccuracy will cause the eventual lock-up of the system. If the mechanical structure is not designed to allow for the operating inaccuracy inherent in the valve, damage may occur.
  • In motor circuits, rigid frames or mechanisms that tie motors together, and/or complete mechanical synchronized motion of the output shaft of the motors, either by wheels to the pavement or sprockets to conveyors, will contribute to cavitation, lock-up and/or pressure intensification.
  • Variations in speed and lock-up can be attributed to differences in motor displacement, motor leakage, wheel diameter variance and friction of wheels on the driving surface.
  • This valve is a divider only; any attempt to flow backwards through the valve is not advised.
  • Below the minimum flow rating there is not enough flow for the valve to modulate. It is effectively a tee. If flow starts at zero and rises, there will be no dividing control until the flow reaches the minimum rating.
  • Incorporates the Sun floating style construction to minimize the possibility of internal parts binding due to excessive installation torque and/or cavity/cartridge machining variations.
