TO320 T - EN - Ed. 04.09 INTRODUCTION Type Description Double dump valve Application sector The double dump valves are ideal for controlled unloading of powder or granular materials; they are mostly suitable for de-dusting and for heavy-duty applications in all industrial sectors. Designed for operating require- ments such as: high temperatures, highly abrasive materials and /or materials with large grain size.
1 - Technical Catalogue GENERAL LAYOUT General layout of VDC with counterweight In VDC with counterweight, the opening of the plate depends on the weight of the material. The force of the material on the plate must overcome the force exerted by the weight on the lever. The working is not regular over time.
TO320 T - EN - Ed. 04.09 General layout of motor-operated VDC The activation of the closure plates is brought about by means of the gear motor, and they are opened by means of a spring. This system (as compared to the gravity system) makes it possible to maintain regular operation also with variable product loads.
1 - Technical Catalogue General layout of pneumatic VDC The opening and closure of the plates is brought about by means of cylinders. The opening/closure duration can be preset according to one's requirements. Like the motor-operated VDC, it is possible to maintain regular operation also with variable product loads.

2 - Operation and maintenance CHECK-LIST IN CASE OF FAULT 1) General questions Description of problem a) Does the VDC start up without problems after long shutdowns? b) Do the atmospheric conditions seem to contribute to the problem? 2) Checking the electrical part a) Are supply current variations possible because a number of machines are started up at the same time? b) Is the plant equipped with a current generator?
TO320 M - EN - Ed. 04.09 RESIDUAL RISKS Although certain risks have been eliminated at the origin in the VDC design and construction phase, certain residual risks still persist for which warning signs and instructions are required for the opera- tors and special measures have to be adopted in the use of the machine.
2 - Operation and maintenance It is therefore the installer’s responsibility to place warning notices which (if the hazard exists) indi- cate the hazard due to the presence of very hot surfaces and the obligation for the operator to use personal protection devices, such as safety gloves.
