Type SEP, pneumatic/hydraulic operated Comparing to the spring operated nozzle, the injection hole of the power operated nozzle can be opened at any time without any pressure lost. Opening and closing of the nozzle is controled by hydraulic or pneumatic advise. The reliable shut-off system separates the melt flow at a predefined point determined by the process. The control of opening and closing is integrated into the unit and very compact. The position of the lever can be choosen at any position. It can be manipulated also machine side by a rod system. © SE System Engineering AG 2011 Options Different tip lengths Filter Mixer Piston position sensor Gasinjection Downloads Dimension sheet for inquiry or order type SEP Flyer Se Shut-off nozzle Easy handling Very compact Opening and closing independet of melt pressure Proven shut-off with high-speed units  (active moving of needle) Back pressure possible until 600 bar Works with filled material (glasfibres)
