basic information
It is used for the safety control of cylinders that repeat vertical movements. In applications where heavy loads are lifted and lowered, it is essential to anticipate unexpected cylinder drops due to power outages or air leaks, especially when there are machines nearby that workers may approach, and to implement measures to prevent this. With two directional control valves, four sensor-equipped PO check valves, and a safety pressure relief double valve, a category 3 solution could be calibrated, but with the CC4, it can be achieved with just one unit, enabling a category 3/4 solution. This significantly enhances safety while also reducing costs related to wiring, piping, and installation, and eliminates the need for a safety pressure relief double valve for load holding circuits.
