Double Acting Type

KSROD

KSROD Product
Design
  • Composite Flat Double Acting Type for Flange
  • Used with installation on Flange without holder
  • Composite/Flat structure ruptured by slit processed on Top disc
  • It consists of Top disc, Seal disc and Vacuum disc
Product Features
  • Can set different rupture pressure for two directions
  • It is applied to low pressure mainly
  • Resistant to corrosion according to Seal Disc materials
  • Precise rupture performance and excellent reliability
  • Vulnerability to pulsation conditions
  • If Teflon in used as Seal Disc material, it is weak to high temperature
  • Limited temperature range by Seal Disc material
Connection
