The Cone Valve system consists of the three main assemblies: an active ConeValve docking and filling/discharging unit; passive valves suitable for connection to different types of mobile containers; and an electro-pneumatic control cabinet with touch-panel, PLC and pneumatic control valves.
Appliance
ConeValve is designed for automatic discharge and accurate controlled transfer of bulk powders from RIBCs (rigid intermediate bulk containers), FIBCs (flexible intermediate bulk containers). An automatic filling application is available with no transfer control required

Working principle
The main mechanical components of the active ConeValve unit are the cone probe, the inner telescopic drive cylinder, the outer cylindrical housing with the locking mechanism, the transfer body with connection flanges and the pneumatic drive motor located inside a protective tube. When the active and passive units are moved into contact, two sensors activate the locking mechanism of the active unit to provide a dust-tight connection between the container and the docking unit. Then the cone probe connects internally to the passive cone valve, unclips and opens it in order to allow the transfer of powder into or out of the mobile container. In discharging mode, the flow of powder can be adjusted continuously by varying and pulsing the stroke of the cone valve via the telescopic cylinder and also by activating the integrated fluidiza-tion. For difficult-flowing, cohesive powders and for accurate dosing, an optional high-frequency vibrator can be integrated into the cone probe.
At the end of the fill/discharge sequence, the cone probe and the passive cone valve are closed. After some air wash sequences, the cone valve is clipped back into the inner ring of the passive ConeValve assembly, thus re-sealing the mobile container, which then can be removed from the docking station.
