basic information
It is used for the safety control of cylinders that repeat vertical movements. In applications where heavy loads are lifted and lowered, and there are machines nearby that workers may approach, it is essential to anticipate unexpected cylinder descents due to power outages or air leaks and to implement measures to prevent them. A category 3 solution that was previously calibrated using two directional control valves, four sensor-equipped PO check valves, and a safety pressure relief double valve can now be achieved with just one unit of CC4, enabling a category 3/4 solution. This significantly improves 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.
