Domed Composite

A versatile, forward-acting disc for low to medium pressure applications

The Domed Composite disc features a non-fragmenting design with a unique tri-membrane construction. This provides improved protection and reliability for low to medium pressure applications.

The disc is suitable for process conditions ranging from 0.3 barg to 17 barg thanks to the combination of a sealing membrane with varying metal options.We pre-form the disc to a specific dome height for accurate burst pressure capability.

Various slotting arrangements are available to suit the requirements of your particular application.

We fit our Domed Composite discs with a Flo-Tel actuator as standard to allow for use our non-invasive, reusable burst detection system. Install the disc using Elfab’s forward-acting rupture disc holder.
