The full time regenerative valve assembly allows a double-acting, single rod cylinder to be
extended more rapidly using the same pump flow. To achieve this, oil from the rod end of the
cylinder is added to the flow to the blind end, increasing the rate of extension.

manifold material, with the port type/size a secondary consideration. Manifolds constructed of aluminum are not rated for
pressures higher than 3000 psi (210 bar), regardless of the port type/size specified.

TECHNICAL FEATURES
Capacity refers to pump flow or regeneration flow, which is the flow coming out of the rod side of the cylinder, whichever is larger
The capacity may be determined by the passages dictated by the sandwich pattern rather than the cartridge capacity.
This valve assembly will not prevent a load from extending the cylinder. The best way to prevent this is to use a vented
counterbalance valve mounted directly to the rod end of the cylinder. A non-vented valve will not work.
The ideal cylinder ratio to use with regeneration is 2:1, the blind end area being twice what the annular area at the rod end. A 2:1
cylinder in regen gives the same speed extending as retracting.
Cylinders with ratios above 2:1 (large rods) will function correctly but with less speed gain. Intensification needs to be considered with
higher ratios. A 2:1 cylinder may generate a pressure on the rod side that is twice system pressure unless steps are taken to limit it.
Cylinders with ratios as low as 1.5:1 (small rods) may work if care is used in designing the application. As the rod diameter gets
smaller in relation to the piston diameter the flows increase dramatically and the force available drops accordingly.
Cylinders with ratios below 1.5:1 are unlikely to result in a working regenerative application because of the small area of the rod and
the high flows that would be generated.
When a cylinder is in the regenerative mode the only force available is the pressure working on the rod area.
Regeneration is only possible in the extend direction.
