Mechanical design
Ring format, grey cast iron or nodular cast iron housing with EPDM liner and multiple
shaft bearing.
The liner is also used to seal the flange. There is thus no contact between the medium
and the valve housing. The valve has a swing-through disc (angle of rotation 360°). The
position of the valve disc is indicated by a notch on the front of the shaft.
