All are certainly not created equal when it comes to Rotary Valves. KREISEL Rotary Valves set the standard when it comes to quality, reliability and when you need something special for difficult applications. KREISEL has a range of specialised rotary valves of which some are unique solutions only offered by KREISEL. Pro-Op Industries have been representing KREISEL in Africa for the last 5 years and together we have positioned the KREISEL ceramic rotary feeder as the market leader in South Africa and we are poised to increase the our footprint in the rest of Africa.
