Zook RLP Rupture Disc

The Zook RLP Rupture Disc is a  Reverse-Acting Low-Pressure Disc.  The Zook RLP Rupture Disc (bursting disc) covers the majority of low-pressure rupture disc applications. Designed to be used in the RLPI Holder.

 

Zook RLP Rupture Disc

The process pressure is applied to the convex side of the RLP Disc placing the dome of the disc into compression. As the pressure rises past 90%, the dome becomes unstable eventually collapsing onto a shear ring that efficiently cuts the disc wide open upon reversal. The state-of-the-art shear ring allows the disc to function on both low pressure and liquid applications.

The RLP-I Series Disc Holder is specifically designed to be used with the Zook RLP Rupture Disc.
