ODM – Rotary valves EZS/VZS

Rotary valves are used for controlled and volumetric dosing or the injection and discharge of fine-grained to coarse-grained, and powdered bulk materials or granulates.

Rotary valves offer a dependable solution for the most diverse technical processes. They can be built under silos and hoppers/bins in order to have a controlled removal and dosing, as well as remove the strain on discharge units such as drag chain conveyors, screw conveyors or belt conveyors.

Rotary valves can be placed prior to dryers or mixers in subsequent, continuous manufacturing and mixing processes, in order to volumetrically dose the removal or feeding of the material. It is possible to improve the accuracy of gravimetric dosing by using rotary valves in combination with weighing equipment.

When dealing with explosive materials, rotary valves can be used to create an isolated system.

Due to their especially compact and modular design, rotary valves can be ideally adjusted to your requirements and material characteristics.

DI MATTEO offers completely new units from scratch and spare parts for your existing equipment.
