[Actuator Construction Case] Hydraulic Control Device for Rotary Printing Press *Without Control Valve

Case study of the hybrid actuator "HySerpack" without a control valve. A hydraulic drive unit without control valves or piping improves printing quality!

We would like to introduce a case study of our hybrid actuator "HySerpack" used in the hydraulic control system of a rotary printing machine that performs multi-color printing and color printing. Rotary printing machines, which are essential for large-scale printing, face significant challenges in improving print quality, particularly regarding the pressure accuracy of the pressure rollers that press the printing paper against the plate cylinder. "HySerpack" maintains pressure accuracy at below several tens of kgf per ton using a hydraulic pressure reduction method, becoming a significant force behind performance enhancement. [Effects] - Maintains pressure accuracy at below several tens of kgf per ton using a hydraulic pressure reduction method - Contributes to performance improvement *For more details, please refer to the PDF document or feel free to contact us.

basic information

**What is HySerpack?** It is a unit-type hybrid actuator that improves the shortcomings of conventional hydraulic drive systems, making it easy to use and assemble. It eliminates piping, which is a cause of oil leakage, and does not use control valves that contribute to complex piping at all. Additionally, it uses an extremely small amount of operating oil, allowing for the use of flammable oil in hazardous locations, and significantly reduces power consumption. **Advantages** ◎ No hydraulic source device, control valves, or piping are required, eliminating the need for hydraulic construction. ◎ Running costs are greatly reduced with power consumption that matches the workload. ◎ Compact, high-functionality, high-output, high-precision, low-noise, and highly efficient, resulting in excellent energy-saving effects. ◎ No cooling wastewater, and the disposal of operating oil waste is maintenance-free, dramatically reducing environmental impact. *For more details, please refer to the PDF materials or feel free to contact us.*
