They are preferred in many processes which require dosage control, batching, silo/hopper/jet cyclone discharging, pneumatic conveying line discharging, air slide conveyor/screw conveyor/airlock, and machine feeding.
Almost any material in powder or granular form of bulk solid can be handled with diverter valves. However, each process is unique and should be handled well. Selecting the most efficient valve for a particular system requires detailed information by collecting correct technical specifications to determine the features of the valve.
Custom design valves are selected by analyzing primarily the intended use of the valve whether it will be used as a solution for shut-off, flow regulation, diverting, converging, venting. Not only the physical properties of the bulk material; sticky, abrasive, corrosive but also minimum and maximum ambient temperature, moisture content determines the construction material such as carbon steel, stainless steel, aluminum, hardox, welded body, or cast body. Furthermore, the inlet and outlet connection shapes and sizes, pressure or vacuum level at inlet and outlet ports, the installation location and type of application whether it requires food-grade, explosion protection, or Atex certification should be considered according to custom requirements.
Each successful application is a result of good observation of the handled material and experience on difficulties and challenges of that specific process. Certain applications might require large diameters, unique inlet-outlet flanges, different sealings, non-standard dimensions, or non-standard body designs.
Handled materials can be any of the bulk solid materials from cement, fly ash, cement clinker, gypsum, perlite, mining minerals, calcium carbonate, pvc, plastic pellets, plastic powders, polyethylene, ceramic powders, alumina, bentonite, wheat, flour, animal feed, seed, corn, bauxite, coal, kaolin, limestone, marble powder, soda ash, urea, sodium sulfate, rice, and sugar.
