Diverters provide unique solutions for specific problems in hydraulic applications, while limiting their tendency to take the path of minimum resistance. If there is no splitter, when you want to split the flow to two or more downstream sub circuits, the path with the lowest pressure will occupy (if not all) the flow. Common designs include valve cores or gear types, which input a single oil passage and output two or more flow rates at a given ratio. Other types of splitters include radial piston type and other volumetric type.The spool type splitter now uses a Y-shaped port body and a clever method of pushing the spool towards the outlet at the lowest pressure. This form of pressure compensation will block the flow on the other side, attempting to use the path with the least resistance to balance the pressure drop through each outlet. However, this method is not entirely accurate, allowing up to 15% or more of the flow to pass through the low-pressure path.The spool type splitter has special characteristics in its operation, requiring the specification of ideal pressure and flow range. If the traffic is less than the specified minimum value, it will become unstable and inaccurate. On the contrary, if the flow rate is too high or the pressure difference is too large, the splitter may only lock one flow path.Because the spool type splitter cannot provide absolute accuracy, hydraulic cylinders may deviate from synchronization, mainly when they do not have a chance to reach the end of their stroke. The spool type flow splitter can use pressure compensated throttling holes to transfer flow from the stop cylinder to the motion cylinder, thereby achieving synchronization. If your splitter does not have an inherent synchronization function, the safety valve installed at the crossover port on both working ports has the same effect.The spool type splitter is not limited to 50:50 flow distribution. For spool types, you may find ratios such as 60:40 or 33:66. You can also customize the ratio, but the most common one is still 50:50.Benefiting from unequal distribution, it is possible to allow two motors with the same displacement to rotate at different speeds, or possibly two motors with different displacements to rotate at the same speed.Gear type splitters are essentially hydraulic pumps/motors connected by a common shaft. Single axis ensures that each gear segment rotates at the same speed, resulting in uniform flow in each gear segment. Gear type splitters are often more efficient than spool type splitters. The fluid loss from one outlet to another is less, while when using a spool type flow distributor, a larger clearance is required to lubricate the spool. Gear type can have up to eight pairs, sometimes even more, which is an advantage over spool type, which generally only has two outlets. However, in order to synchronize the gear type splitter, a safety valve must be installed at each outlet to send the liquid back to the splitter inlet from the stopped cylinder or motor.Most diversion valves are also confluencers, which means they can achieve movements such as cylinder contraction and extension. In combination mode, synchronization still occurs, which helps to keep multiple actuators synchronized in both directions at the end of the stroke. Gear splitters can be used as confluencers, but spool splitters may not always be.The other two types, radial piston type and volumetric distributor, have relatively high synchronization. The radial piston type divides a single flow into two output flows, providing high volumetric efficiency and low-speed capability. The volumetric splitter works by exchanging volume between the volume synchronizer and the working cylinder. They are most suitable for high-precision applications that require low pressure drop.
