In applications with bulk solids, a number of factors must be taken into account to ensure that fine dosing and container emptying run in a process-optimised manner. The right control technology is crucial to prevent bridging.

Especially when used with abrasive bulk solids, the right shut-off valve makes the decisive difference for safe metering technology. Warex Valve offers special butterfly valves that provide control with extended service life and a maintenance-free design without the need for subsequent lubrication. The APS® design ensures pressure tightness and safety with abrasive media.

Do not underestimate bulk material hazards

When filling, storing or emptying bulk solids, compaction or jamming can occur. Here, the plant operator must assess the individual risks. Hazards can arise from sinking, cavity or bridge formation, which are difficult to assess from the outside. Valves used in silos must guarantee the safety of reliable closing to ensure trouble-free bulk material handling. The butterfly valves of the Rotary Valve series DKZ 103/110 APS® are suitable for applications of this kind, because the Air-Pressure-Sealing design ensures constant pressure tightness even with slight signs of wear. The Rotary Valves DKZ 103/110 APS® from Warex Valve are special valves for an even control of the bulk material flow and for the reduction of bridging during continuous conveying and tight shut-off of bulk materials and granulates. The butterfly valves are also available in an explosion-proof version for use in zone 0 / 20, in accordance with type examination BVS19AtexH034X.
