DIN 3352 F4 with a rising stem: the F4 is a face-to-face length, so this valve drops into a European pipe run built to that dimension without a spool piece. Rising stem means the position is visible, which is what a fire line or a plant isolation point wants. PN10/16, DN50–DN600, ductile iron GGG40/50, fusion-bonded epoxy, EPDM wedge. If the line is to be buried, the same F4 body comes with a non-rising stem — the dimension is fixed by the pipe, the stem by the installation.
