An economic solution for very low pressure aseptic and sanitary (hygienic) applications

This forward acting rupture disc has a composite design with a unique tri-membrane construction. This non-fragmenting disc offers enhanced protection, reliability and leak tightness for very low burst pressure applications. The ferrule allows installation within most sanitary clamps and fittings, including tri-clamps and PED connection types.

We can also manufacture the disc with various slotting arrangements to meet customers’ specific application requirements.

The BioFlat Composite disc is fitted with a Flo-Tel actuator as standard and is compatible with our sanitary Vent-Tel burst detection system.
