Alphadock split butterfly valve, also called high containment valve, consists of active valve and passive valve. It is designed for material sealing and sterile transfer, preventing cross-contamination and protecting operators and working environment. Widely applied for material loading, unloading, batching, milling and sampling under isolated conditions.
During docking transfer, the active valve and passive valve couple into an integrated unit. When the butterfly valve opens, material feeding and distribution proceed. After material transfer finishes, close the butterfly valve, release the fastening hand lever, then separate active and passive halves. Each equipment side remains sealed for independent transport to maintain isolation.
This split butterfly valve achieves OEB5 containment level. Complete supporting documents are available to satisfy high-end domestic and overseas customer requirements. It has gained global recognition from Roche, Novartis, Copenhagen Atomics Aps, Fette Compacting, Harro Höfliger, Envair, GEA and other well-known enterprises, optimizing modular solid pharmaceutical processing workflows.
Key technical advantages:
High-containment sterile material transfer, solid powder loading/unloading, batching, crushing and sampling in pharmaceutical solid dosage production.
1. Leakage limit OEL<1µg/m ³ (OEB5-compliant), adding a vacuum cleaner can lower the value;
2. Proven mature technology, with a maximum allowance of ± 14mm for docking;
3.180 ° symmetrical design, flexible docking position;
4. Modular design of material contact components, easy to replace;
5. Customized, integrated, and highly automated to meet high-end needs.
Size series:
DN50/100/150/200/250/300
