The new Uni-Guard from Elfab is a scored reverse bursting disc ideal for very low pressure applications in aggressive process environments.
The new Uni-Guard from Elfab is a scored reverse bursting disc ideal for very low pressure applications in aggressive process environments.
Incorporating all the benefits of the original Uni-Guard disc, the new device includes several new design features allowing it to operate with increased precision.
Bursting discs are pressure relief devices used throughout the processing industries.
Designed to burst at a specific pressure, they prevent potentially dangerous pressure build-up and are now an essential safety component in process plants.
With a burst pressure range between 0.5 to 12 bar g and an operating temperature range of -40 to +200C, the Uni-Guard is both gas and liquid compatible.
It has a performance tolerance of +/-5%, a maximum operating ratio of 90% and a very high cycle life (typically over 100,000 cycles).
The Uni-Guard can be combined with Elfab's Integral Flo-Tel sensor to create a high-precision detection device which instantly sends a signal to process control systems when the bursting disc has operated.
It is also suitable for hygienic applications, having a smooth surface on its process side which eliminates the danger of product build-up.
In addition, the disc is non-fragmenting so will not contaminate the process after functioning.
