The mixproof butterfly valve is used for separating media. The valve disk (1) as
the shut-off element is supported between two flanges screwed together (2, 3)
and plain bearings (5). The valve positions are OPEN / CLOSED.
In the CLOSED position, two media can be reliably separated from one another.
The leakage cavity is open towards the atmosphere in this case. After switching,
the medium in the valve disk leakage areas can drain by gravity (7).
In the OPEN position (maximum throughflow), the leakage paths towards the
atmosphere are closed. The leakage cavity is sealed by the radial seal (6) on the
short valve disk shaft.
Hint!
The hole (B) in the square end is used to indicate the position of the
valve disk.
