INTEC K220-S-FS-DE Ball Valves

Cavity relief with both sides spring loaded seat rings.


By means of double loaded seat rings the input-side seat will be pushed back at 2 bar higher pressure in the cavity, with the result, that the pressure in the cavity escapes to the inflow side. The ball valve may be used due to its double loaded seat rings in both directions.

  • Safe relief of the cavity, also in critical media
  • Pressure relief from 2 bar higher pressure in the cavity to the upstream.side
  • Bi-directional service
