In the construction chemical, environmental or mineral industry they handle specific abrasive products like glass cullet, carbon, cement, dolomite, quartz and more. They are exposed to important effects of abrasion. The wear of the rotor but also of the body happens even if the rotary valves are made of hardened materials and alloys. Such treatment will prolongate the working life but will not avoid the abrasion completely.
The conclusion is that sooner or later, the rotary valve has to be undertaken a revision and worn out parts have to be replaced. Otherwise the leakage will increase, and the operation and
