Rotary Valves

Self cleaning rotary valves:

The self cleaning rotary valves areĀ used for bulk-solids dosing, sealing, feeding, discharging, and measuring of adhesive,
bridging bulk products and products that tend to cause blocking. The ultra-compact welded structure enables both individual adjustments and a multitude of housing and rotor versions.
Rotary valves are used to process a wide variety of bulk materials, including ashes, coal, cement, sewage sludge, polymers, crystalline acids, methyl cellulose, and carbon black, as well as any other dusty or grainy product.
Rotary valves operate according to the principle of volumetric conveying, A defined discharge rate sets in based on the rotary valve geometry and speed.
The forced cleaning rotary valves offers controlled conveying of all bulk materials that could not be handled by a non-self-cleaning model.
Koellemann product range covers all the required options, designs and materials. Depending on the intended use, we offer heated or cooled self-cleaning rotary valves or with add-on features such as leakage air collectors and overfill protectors.

Rotary Valves:

We offer specialized rotary valves for metering, sealing, feeding, discharging and measuring bulk
products for sophisticated areas of application. Simple rotary valves operate according to the principle of volumetric conveying. Here the bulk product falls by gravity into the mostly
star-shaped chambers in the inlet area of the rotary valve. By rotating the rotor, a defined quantity of bulk product is conveyed to the discharge area. A defined discharge rate sets in based on the rotary valve geometry and speed.

Among other things, we offer high-pressure and high-temperature rotary valves and forced clearing rotary valves for adhesive and bridging bulk materials that, depending on their intended use, can be heated or cooled or equipped with add-on features such as leakage air collectors and overfill protectors.
