Benefits

  • Additional features ensure safe sealing to atmosphere: Risk of leakage is reduced by internally mounted hinge pin. The hinge pin mounting bracket is welded directly to the inside of the cover, so no additional seal to atmosphere is required.
  • Reliable, tight shut-off and service-friendly design due to flexibly mounted valve disc. Precise alignment of valve disc with body seat; valve disc is easy to replace.
  • Hard-faced seat/disc interface made of wear-resistant and corrosion-proof 17 % chrome steel or Stellite for long service life and high functional reliability.
