***Disclaimer: The following summary contains information gathered from various sources such as product descriptions, technical specifications and catalogs. 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 FSFDXAV (Material Number: FSFDXAV) is a sliding-spool, pressure-compensated flow divider valve designed to split oil flow into two different branches of a hydraulic circuit at a designated ratio. This valve is ideal for applications requiring unidirectional hydraulic motors, hydraulic cylinders where flow division in one direction only is necessary, and multiple circuits serviced from a single pump supply. The FSFDXAV features physical interchangeability with other flow divider and divider-combiner cartridges, maintaining the same flow path and cavity for a given frame size. It operates by directing the higher percentage of flow to the circuit leg with the greatest load in dividing mode. However, caution is advised when using rigid mechanisms to tie actuators together, as this may lead to cavitation or system lockup due to operating inaccuracies inherent in the valve's design. In motor circuits involving rigid frames or synchronized motion mechanisms, users should be aware of potential cavitation or pressure intensification issues due to variations in motor displacement and friction on driving surfaces. The FSFDXAV functions solely as a divider; reverse flow is not recommended. It supports divisional accuracy ranging from 6.5% at minimum input flow to 3.5% at maximum input flow, with pressure drops of 30 psi at minimum rated input and 250 psi at maximum rated input flows. The valve accommodates rated input flows with various split ratios and incorporates Sun's floating style construction to minimize binding risks during installation or due to machining variations. It fits into T-34A cavities and operates under a maximum pressure of 5000 psi (350 bar), making it suitable for demanding hydraulic applications requiring precise oil distribution control within specified parameters.

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.
  • Dividers with unequal ratios have the higher flow at port 4.
  • 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.
