The Model PD, Proportional-Type, Pressure-Compensated Flow Divider offers an efficient means of proportionally dividing a single flow of hydraulic oil. The flow ratio from the outlet ports remains constant despite load differences between the ports. Outlet flow ratios are preset at the factory and a range of ratios from 50/50 to 90/10 are available. Flow through the Model PD Divider cannot be reversed. It is a flow divider only - not a flow combiner. A Model PDC with a combiner feature is offered by substituting a combiner spool assembly for a standard spool. This feature not only divides flow, but flow may be combined in reverse direction and synchronized in both directions. It is only available with a 50/50 flow dividing ratio. Neither model, however, should be constructed as a flow regulator. If other ratios are required with the combiner feature, contact us.
The RD-400 is a constant volume priority divider. It can be used in applications where two circuits are to be supplied by a single pump such as power steering sytems. In operation the flow of oil supplied to the inlet is divided into two flows, the priority flow and the excess flow. The priority flow will remain nearly constant with variations in pressure on either the priority or excess flow port and will also remain nearly constant with variations in the inlet flow. The RD-400R provides the same function as described above with the addition of a built-in pressure relief for the priority port only. This relief is factory set at 1500 psi.
The RD-500 is an adjustable constant volume priority divider. This valve provides the same function as the Model RD-400 except the priority flow is adjustable from 2 gpm to 12 gpm. The priority flow is set using the adjusting screw and is then locked in place to maintain setting. This allows setting to be fine tuned in the field to the exact flow needed.
The RD-500P is a pressure compensated propertinal flow divider with one fixed and one adjustable orifice. On this valve, the divider ratio can be changed in the field.
