DOEBRITZ CONE VALVE,HIGH-FREQUENCY VIBRATOR/ATEX CERTIFIED

Doebritz Cone Valve Full Industry Brochure

Brand:Doebritz

Product: Cone Valve

Positioning:For automatic filling, discharging and dosing of powders

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.

Highlights

• Dust-free  Closed process
• Fully automatic
• Accurate dosing
• Universal compatibility with different types of containers

Working principle

The active Cone Valve system’s core mechanical assemblies comprise a conical probe, inner telescopic drivecylinder, lock-equipped outer cylindrical housing, flanged transfer body, and a pneumatic drive motor enclosed within a protective tube.

When docked with a passive unit, twin sensors actuate the active unit’s lock to form a dust-tight seal between the container and docking station. The conical probe interlocks with the passive cone valve to open it,permitting bidirectional powder transfer with mobile vessels. Discharge flow is steplessly controllable through continuous/pulsed cylinder stroke adjustment and the built-in fluidization system. An optional high-frequency vibrator fitted to the probe serves cohesive, low-flow powders and precision dosing tasks.

Once filling or discharging finishes, the probe and passive valve shut down. After multiple air purge cycles, the cone valve latches into the passive unit’s inner ring to re-seal the mobile container, allowing its safe detachment from the docking station.

Electro-pneumatic control

The control system for the automatic operation of the active ConeValve unit includes a touch-screen operator panel,a PLC (Programmable Logic Controller), and pneumatic control valves — all housed within a steel cabinet. Connection to the active ConeValve is achieved via three multi-tube hoses and one electrical cable, each equipped with quick-connect sockets. The dedicated software enables full control and monitoring of all functions of the active.ConeValve unit and supports communication with other PLC and SCADA systems via a BUS network.

Passive ConeValve for mobile containers

• A variety of passive ConeValve models are available to suit the inlet or outlet of different types of flexible and rigid mobile powder containers, such as big bags, steel or plastic bins, and drums etc.
• The passive valve consists of 3 main components: the cone valve, the internal clamping/fluidization ring, and the external docking ring with a Tri-Clamp flange, along with various internal and external seals.
• The connection to the mobile container depends on the type and the execution of the latter and can be either permanent (e.g. for flat-top or flat-bottom big bags) or removable/reusable (e.g. for big bags with filling/discharging spouts, or rigid containers with standard Tri-Clamp flanges).
• Once connected to the mobile container, the passive ConeValve allows automatic docking and filling/discharging of the bulk powder as described above.
