We would like to announce special directional control valves and gear pumps for log splitters.
These applications require a high volume at low pressure for rapid extend of cylinder, and then low volume at high pressure for splitting wood.
In a typical log splitter, a user operates a control valve to route fluid from the pump to the cap end of the cylinder. The combined flow from the tandem pump extends the cylinder’s piston rapidly to reduce the time it takes to advance the wedge to engage the log. Once the wedge engages the log, the log resists further extension of the cylinder, and pressure increases.
At second phase, a large displacement pump disengages and a smaller pump moves the piston rod at lower speeds. This can achieve higher pressure to split the wood.
