INTEC K220-S-DE - cavity relief

Cavity relief with both side spring loaded seat rings of a floating ball valve design.

By means of double loaded seat rings the input-side seat will be pushed back at 2 bar higher ressure in the cavity, with the result, that the pressure in the cavity escapes to the inflow side. The automatic pressure relief device provides a safe relief of the cavity by not allowable high pressure increases. The ball valve can be used in both directions, the cavity relief works with all expanding media.
