Safety Valve for Pressure Vessel Manufacturer

This is a composite disk comprised of three parts:

  1. A slotted metal top section is the pressure-controlling element.
  2. A Teflon seal isolates the top section from the process.
  3. The slotted metal bottom section will withstand a vacuum. The flat design minimizes the possibility of disk damage during installation. This rupture disk is suitable for chemical reactors, heat exchangers, and textile processing house machinery.
Rupture Disk For Pressure Vessel Surat

The simplicity of the ZD Rupture Disk Holder design incorporates several features that allow easy installation. Asymmetric alignment pins in the disk holder mate with location holes in the replacement disk, thus eliminating incorrect installation and slippage. The flat-set design, in combination with a metal-to-metal “bite type” seal, provides a leak-tight system. The ZD holder and rupture disk are easily pre-assembled with side lugs.
