Stainless Steel Split Butterfly Valves (SBVs): High-Containment Transfer Solutions

Superior Containment & Contamination Control

In the handling of potent APIs, toxic granules, and sterile powders, maintaining a sealed environment is critical. Our Stainless Steel Split Butterfly Valves (SBVs) provide a state-of-the-art containment solution, engineered to protect both the operator and the product during material transfer.

By utilizing a precision-engineered “Active/Passive” docking mechanism, our SBVs ensure a dust-free transfer path, achieving high containment levels (down to OEB 4 / OEB 5) and ensuring total GMP compliance.

Technical Specifications & Materials

Body Material: 316L Stainless Steel (ASTM A270 / DIN 1.4404) for maximum corrosion resistance and durability.
Surface Finish: Internal polishing up to Ra < 0.4 µm (Mirror Finish) to prevent powder adhesion and facilitate cleaning.
Sealing Materials: FDA-compliant EPDM, Silicone, or PTFE.
Size Range: DN50 to DN300 (Custom sizes available upon request).
Operation: Manual or fully automated (Pneumatic/Electric) docking systems.

How the Split Butterfly Valve Works

The SBV system consists of two distinct halves that only allow flow when safely interlocked:

The Active Half: Typically mounted on the process equipment (e.g., Reactor, IBC, or Filling Machine).
The Passive Half: Mounted on the portable container (e.g., Drums, Bags, or intermediate bins).
Docking & Transfer: Once docked, the two halves form a single internal butterfly disc. The seal remains intact during the entire rotation, ensuring that no dust escapes into the atmosphere and no external contaminants enter the process.

Core Advantages for Your Facility

1. Enhanced Operator Safety

Significantly reduces the need for heavy Personal Protective Equipment (PPE) by containing hazardous or potent powders within the valve assembly during the entire transfer cycle.

2. Product Integrity & GMP Compliance

The sealed transfer path prevents cross-contamination between batches, ensuring the highest standards for Aseptic and Sterile transfers in biotech and pharmaceutical manufacturing.

3. Reduced Cleaning & Validation Time

Our split butterfly valves are designed for CIP (Clean-in-Place) and SIP (Sterilize-in-Place). The precision 316L stainless steel construction minimizes “dead zones,” reducing the time and cost required for cleaning validation.

4. Versatility & Flexibility

While our standard valves are made of robust stainless steel, we also offer integration options for Single-Use (Disposable) Passive Valves to further reduce cleaning requirements in multi-product facilities.

Applications

Pharmaceutical: Transfer of potent APIs, tablet compression, and capsule filling.
Biotech: Sterile addition of media or ingredients to bioreactors.
Fine Chemical: Handling of toxic or highly reactive granules.
Food & Nutrition: High-purity ingredient dosing.
