Description

OsecoElfab's PCR is a reverse buckling rupture disc designed for high cycling or high vacuum gas and vapor applications. This disc is commonly used in SF6 switchgear applications to prevent catastrophic explosions due to arc flash events. The disc activates in milliseconds to provide quick, safe discharge of gases, heat and pressure.

The scored petals on the disc dome are designed to be non-fragmenting, offering increased protection for personnel. The corrosion-resistant design provides a longer service life and greater environmental protection.

  • Size Range: 1"-12" DN25-DN 300
  • Service Type: Gas
  • Operating Ratio: 90%
