Manufacturers of mining machinery, oil and gas plants and chemical plants can now also use the tried-and-tested PSL-CAN directional spool valve with onboard electronics from HAWE Hydraulik in potentially explosive atmospheres. The actuating head has been redesigned to comply with current regulations such as ATEX, IECEx, MA and CCC. The combination of intelligent valve control, simple commissioning and compact design is thus finding its way into many other areas of application. This creates the prerequisite for fully automated operation, even underground, e.g. in a man-free mine.
