Operating Instructions EBE 350 VH
General
3.8 Operating elements
The shot valve
Between the abrasive storage hopper and the blast housing there is a
valve in order to control the abrasive flow towards the blast wheel. Any
change in the opening of the valve causes the amount of abrasive fed
to the blast wheel to change. The change in the abrasive fed can be
read from the ammeter. The valve is operated by the shot valve
actuator and can be adjusted so that any quantity of abrasive can be
fed to the blast wheel. Optimum blast cleaning power is reached when
the ammeter indicates 15 - 20A. It is not permitted to blast with a higher
current value.

The shot valve actuator
This component is located at the front side of the hopper and
regulates the shot valve to control the flow of abrasive towards the
blast wheel. While pushing the “+” button,
the shot valve will open and
abrasive is allowed to travel towards the blast wheel in a progressive,
controlled manner (max. 20 A). While pushing the “-“ button, the shot
valve will close.
