The Lauridsen Industri model 1400 was particularly designed for the use in silo and container discharge range. The special funnel-shaped body enables an easy flow of the medium, like for example powder or granulate. Mediums with high solids content also belong to the application of this valve. If solids accumulate in the sealing area, it can be blown free by compressed air via the standard flush connection. The valve should be mounted horizontally below the silo so that that the expected operating mode can always be warranted. The different available sizes, pressure stages, materials and drives are shown in the column on the right. Please contact our sales department for special executions
