ABSTRACT:
The invention relates to a seat valve in which a ball-shaped valve element is held in a sleeve which has control edges which cooperate with an opening arranged between the valve seats and connected to a connection. On switching over of the valve element from one valve seat to the other a positive switching overlap of the seat valve is achieved and with relatively small ball diameters large flow rates can be controlled.
