Many options and extras for MD rotary valves
VDL Industrial Products rotary valves can not only be used as an air trap under dust filters and cyclones or as a dosing device under screw conveyors, but also as a drainage device for dry substances from eg silos. After extensive research, these MD valves have been developed for dosing and transporting powdered and granular products. The rotary valves from the MD series have since been expanded with the MD250 and the MD300.
Because of their construction, these very robustly designed valves combine a high degree of filling with minimal product damage, so that a smaller valve is sufficient. With the design of the MD, maintenance-friendliness has already been taken into account through the use of external ball bearings and adjustable bushings, a direct flange drive, an easily removable rotor and standard DIN PN 10 connection flanges.
The ball bearings do not come into contact with the product in this way, so that it cannot cause extra wear.
For pressure differences up to approx. 1 bar, the standard version with cast-iron housing is sufficient. Special wear-resistant, non-stick and / or food grade coatings are also possible.
The MD rotary valves are not only fast but also easy to clean.
The EX version is flame-resistant and shock-resistant up to 1.7 bar with Vulkollan blades and 2.5 bar with steel / stainless steel blades and is equipped with aeration as standard.
In order to be able to provide optimum service in the choice of the lock, the VDL engineers have designed and constructed a test installation to be able to test product properties in-house. This way we can fully adjust the lock to the wishes of the customer.
