A valve arrangement has an outflow seat section defined by at least a tubular side wall. The outflow seat section has a free end with an engaging part extending along the entire periphery of the side wall. The engaging part is adapted for close engagement with an engaging surface of a movable obturating plate. The engaging surface is substantially parallel to a plane of the engaging part and remains substantially parallel to this plane during movement of the obturating plate toward and from the free end of the outflow seat section. During operation of the valve arrangement the engaging surface of the obturating plate simultaneously engages the entire plane of the engaging part of the outflow seat section causing closing of the valve arrangement.

A valve arrangement, comprising: an outflow seat section defined by at least a tubular side wall, said outflow seat section having a free end with an engaging part extending along the entire periphery of the side wall, said engaging part being adapted for close engagement with an engaging surface of a movable obturating plate, said engaging surface being substantially parallel to a plane of said engaging part and remains substantially parallel to said plane during movement of the obturating plate toward and from said free end of the outflow seat section, whereby during operation of the valve arrangement said engaging surface of the obturating plate simultaneously engages the entire plane of the engaging part of the outflow seat section causing closing of the valve arrangement, while simultaneously and proportionately moving and spacing the obturating plate away from the entire plane of the engaging part of the outflow seat section during movement of the obturating plate by operating means so as to permit cleaning means to be activated to clean the entire face of the obturating plate when it has moved proportionately away from the entire plane of the outflow seat section.
