LENS GASKET

Description:
Lens Gasket are made from a solid stainless steel disc or special alloys.
They are particularly used in the fertilizer production industries, installed on check valves, shut-off valves and high-pressure valves.
The construction standard provides for the execution according to DIN 2696 standard.

  • Ideal in the presence of very high pressures
  • High compressive strength
  • Wide choice of structural conformations and types of alloys
