They are used for the leakage-free isolation of pressurized working circuits (e. g. pressing cylinders). Due to their aerodynamic design and the relatively little closing force of the compression spring (6) at the main poppet, they are particularly suitable for the pulling function and for filling e.g. the main cylinder at presses during the fast closing movement. The integrated pressure connection P allows for the high pressure build-up in the pressing cylinder!
