In doing so, an increase in throughput performance of up to 20%. An optimized inlet geometry is provided for gentle and anti-chopping operations. The “anti-chopping” inlet deflects the product into the rotating rotor chambers of the valve and can reduce produce degradation. Furthermore, the transformation of the elongated opening to a pipe connection was integrated in the cast. An additional consequence of the reduction in noise emission is that an adapter piece is no longer required. The ZV valve also now has a pipe connection that meets the standard.
