SEP Power Operated Shut-Off Nozzle
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 by pole or cable. If the melt pressure exceeds 600 bar, the nozzle opens automaticaly.(safty device). Our system is standard wear protected.All hydraulic actuators with water cooling.
