Valve papillon split par
A two-part containment valve whose active and passive halves seal separate vessels, then dock and open as one butterfly disc for powder transfer.
- Active and Passive Half Valves
- Closed Docking Sequence
- Contained Powder Discharge
- Manual or Automated Actuation
Introduction de produit
The split butterfly valve connects a source container to a receiving vessel without leaving one open valve face exposed. Each half closes its own container. After docking, the two disc halves lock together and act as one butterfly valve; powder transfers through the combined bore, then the valve closes before undocking. The active half contains the drive mechanism, while passive halves can remain on multiple bins or bags. Valve diameter, seals and cleaning method are selected for the powder and process.
Key Features
Docking joins the two exposed disc faces before the transfer bore opens.
One active actuator can operate compatible passive units on multiple containers.
Free-orientation or guided docking options accommodate container alignment.
Removable product-contact parts support inspection and cleaning.
Préoccupations du client produit
Contained powder transfer depends on the two valve halves aligning, sealing and completing the correct close-before-undock sequence.
Opening a conventional valve exposes the mating face to powder.The split discs join their exposed faces before the combined bore opens.
A suspended IBC is difficult to align precisely.Guided or free-orientation docking tolerates normal positioning variation.
Operators disconnect while the disc remains open.Mechanical interlocks block separation until the combined valve is closed.
Product residue remains on complex valve parts.Quick-release product-contact components allow planned cleaning or changeover.
