Multi-Stage Radial Piston Flow Dividers

The FDM radial piston flow dividers provide pressure-indipendent division of a flow into a maximum of 10 equal parts or eventually in different division ratios. Thanks to the high volumetric efficiency and low speed capability of the radial piston construction type, is possible to obtain dividing precisions up to 99% and excellent controllability even at low oilflows. Integrated reset valves grant misalignments compensation at end-stroke and protection against pressure peaks and cavitation.


- two-stages and multi-stages flow dividers
- high cavitation resistance
- accuracy: up to 99%
- wide working range
- add-on relief & cavitation valves
- different synchronization ratios available
