INTRODUCTION1.
Type1.1
VDC
Description1.2
Double dump valve
Application sector1.3
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. They are
also suitable for systems that do not require continuous ow of material.
Contraindications1.4
VDC valves are not suitable for conveying materials that are not owable in compliance with the
required quality standards.
VDC valves are not designed for operating in hazardous conditions or with hazardous materials.
Hazardous materials are those that are:
• Explosive;
• Toxic;
• Harmful;
• Inammable
Operating temperatures1.5
External temperatures -10°C to +50°C
Max. temperature of conveyed material 500°C.

GENERAL LAYOUT2.
General layout of VDC with counterweight2.1
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.

General layout of motor-operated VDC2.2
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.
