Metal extruder bursting disks
Series S-EB
Types S-EB / S-EB-SVT
The S-EB series provides the overpressure protection of extruders as a purely passive safety element in addition to pressure and temperature sensors. The bursting disk body is screwed into the extruder housing in a manner that the bursting disc is positioned as close as possible to the product. Thus the bursting disc is not blocked by product deposits and can be opened unimpaired, in order to relieve unwanted overpressures – this is the only way the sensitive machine components can be protected reliably.
Design examples
S-EB 45mm long
S-EB 460mm long
