The ZAP & KBA rupture discs have the media pressure acting on the convex side of the rupture disc, placing it in compression. When the burst pressure rating of the rupture disc is reached, the compression loading on the rupture disc causes it to reverse, snapping it through its neutral position and through the knife blades resulting in a full opening.</div> </tD> <tD VALIGN=CENTER WIDTH="48"><IMG BORDER="0" SRC="1x1.gif" HEIGHT="181" ALIGN="bottom" WIDTH="48" HSPACE="0" VSPACE="0"></tD> <tD VALIGN=CENTER WIDTH="248"><IMG BORDER="0" SRC="1x1.gif" HEIGHT="181" ALIGN="bottom" WIDTH="248" HSPACE="0" VSPACE="0"></tD> </tR> </TABLE></div> <bR> <div> <B>For more information call (330) 253-4800or email: sales@prdtechnologies.com</B> </div> <bR> </td> </tr></table></body>
