ViDos – This solution is based on the established valve series Z 600. Body, disc and liner are standard elements of the EBRO Product Program.
A vibrator mounted on the lower shaft makes this valve special, as it causes a linear vibration which swings the disc horizontally.
The frequency of this vibration is controlled via air pressure.
Application:
Reduction of crustification and adherence
When used as a shutt-off valve, the vibration function helps to reduce the crustification of particles within the product. This leads to significant extension of the Cleaning- and Service periods.
When the valve remains in the closed position for a long time, adherence of the conveyed product is a consequence. Disc and liner are subjected to high frictional forces when opening the valve.If the vibrator is switched on before opening, crustification of the product will be dispensed.
Fine Discharging / Dosing
When equipped with a positioner, different positions for fine and rough dosing are possible. Having reached the dosing position, the vibrator will be set into operation, thus keeping the product in motion. So the “Bridging effect“ is prevented.
The product can be conveyed very sensitively even with minor opening angles.
