| description | A 3/2 directional poppet valve is provided having a pilot poppet valve and a main valve. Said main valve comprises a housing having a longitudinal bore within which two 2/2 cartridge or logic valves are arranged in an axially opposite manner. A spool is provided in each of said logic valves. The diameters of said spools being different and the front ends of said spools facing towards each other can be mechanically coupled such that the movement of the one or the other spool into the closing position causes a movement of the other spool out of its closing position. |
