Hydraulic Blocks

Valve blocks for mounting to directional control valves

System of modular blocks with possibility for mounting of directional control valves

Blocks with sequence valve block

Hi-low unloading blocks for tandem pumps

Many systems require a high volume at low pressure for rapid traverse of a vise or tool, and then low volume, high pressure for clamping or feeding. This can be accomplished by a hi-low circuit using two pumps. During rapid traverse, both pumps supply the system. When pressure rises during clamping or feed, the large-volume main pump unloads, and the small pump maintains pressure. Output flow of the small pump is low enough to prevent heating of the oil.
