The Sun Hydraulics FSCAXAV (FSCAXAV) is a closed-center flow divider/combiner valve designed for precise hydraulic control, particularly in applications requiring bidirectional operation of multiple cylinders or hydraulic motors. This sliding-spool, pressure-compensated device effectively splits flow in one direction and combines it in the opposite direction. It is ideal for synchronizing actuators, although it should be noted that synchronization is not perfect due to inherent inaccuracies that accumulate over time. The valve's compensating characteristics favor the circuit leg with the greatest load during dividing mode and the one with the lowest load during combining mode. This can lead to cavitation or system lockup if rigid mechanisms are used between actuators without accounting for these inaccuracies. The FSCAXAV model features a T31A cavity and belongs to Series 1, offering a capacity range of 1.5 to 8 gpm (6 to 30 L/min) with a maximum operating pressure of 5000 psi (350 bar). Its divisional accuracy at minimum input flow is rated at \u00b14.5%, improving to \u00b12.5% at maximum input flow. The valve experiences a pressure drop of 30 psi (2 bar) at minimum rated input flow and up to 350 psi (24 bar) at maximum rated input flow. The hex size of this valve is 7/8 inch (22.2 mm), and it requires an installation torque between 30 to 35 lbf ft (41 to 47 Nm). Weighing approximately .60 lb (.30 kg), this model incorporates Sun's floating style construction, minimizing potential binding from excessive installation torque or machining variations within the cavity/cartridge interface. While this valve does not provide leak-proof holding capability, its design helps minimize cross-flow and drift between ports through controlled spool leakage, making it an effective solution for applications where divisional and combining accuracy are critical within specified flow ranges.

Closed-center flow divider/combiners are sliding-spool, pressure-compensated devices used to split flow in one direction and combine flow in the opposite direction. These valves may be used to accurately control two or more cylinders or hydraulic motors where bidirectional operation is required.
- 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 combining mode, compensating characteristics will cause the leg of the circuit with the lowest load to receive the higher percentage of flow. If a synchronization feature is not included, an additive accuracy error will be experienced with each full stroke of the actuator.
- 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.
- Extreme pressure intensification can occur on multiple wheel drive vehicles.
- Flow between ports is limited to spool leakage. This does not provide leak proof holding capability, but can be useful in minimizing cross flow and drift.
- Divisional and combining accuracy are equal.
- 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 or combining 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.
