Features

The KN rubber-steel gasket 9107/KN consists of a metal support ring and a speciallymolded, replaceable elastomer ring which is located in the force shunt after fitting. The support ring also acts as a centering ring and force limiter. It thus both absorbs the bolt forces needed for high pressures and protects the rubber seal against overcompression.

Advantages

  • The outer ring (EPDM) can be reused after replacement
  • Uniform distribution of the surface pressure

Operating range

Pressure: p = 64 bar
Temperature
  • Continuous operation:
    t = –30 °C ... +120 °C
  • a few hours:
    t = –30 °C ... +150 °C
  • a few minutes:
    t = –30 °C ... +200 °C
Recommended surface roughness:
RZ ≤ 100 µm

Load values (q) elastomer seal
The surface pressure acting in the flange block position is:
  • at room temperature:
    qmax. = approx. 10 MPa
  • at 100 °C:
    qmax. = approx. 6 MPa

Materials

  • Sealing ring: EPDM
  • Support ring: St 37 galvanized, chromated or stainless steel

Notes

With coated flanges, we recommend selecting the outer diameter of the coating so that the sealing lip on the atmospheric side lies in the steel part. If necessary, discuss the dimensions with your EagleBurgmann contact.

Forms of supply

  • Standard dimensions as defined in the EagleBurgmann in-house standard for DIN flanges or for flanges to ANSI B16.5 and MSS SP-4.4
