The valve unit includes a spindle movable in vertical direction in the housing and is connected to a valve disk which reciprocates in a flow cylinder having a perforated casing.

The valve unit of the valve is insertable into the housing and removable therefrom in its entirety without necessitating a dismantling of the housing.
