Alfa Laval Unique DV-ST UltraPure Diaphragm Valve - PW & WFI Control
The Alfa Laval pharmaceutical purifier valve is an aseptic diaphragm-style control point used to maintain, stop, or regulate flow in high-purity process systems. Commonly specified for Purified Water (PW) and Water for Injection (WFI) distribution loops, it supports sterile, contamination-free fluid handling in pharmaceutical and biotechnology applications.
Valves such as the Unique DV-ST UltraPure focus on hygienic design features that help reduce bacterial build-up, support drainability, and provide practical diaphragm integrity checking via a leak detection feature.
Key specs and features
- Aseptic diaphragm / regulation valve concept for sterile service
- Crevice-free, hygienic design intent to help limit bacterial build-up
- Often self-draining design to support cleanability
- Leak detection hole for quick identification of diaphragm failure (design dependent)
- Flow regulation and shut-off capability for high-purity loops
- High-grade stainless steel with low delta-ferrite (stated benefit: helps minimise rouging in high-purity water systems)
- Designed to meet stringent sanitary standards (e.g., ASME BPE)
- Documentation (Q-doc) for compliance support and traceability
Options
- Shut-off duty vs modulating / regulation duty (application dependent)
- Diaphragm materials and configuration (to suit media and cleaning regime)
- Traceability documentation pack (Q-doc)
- Installation orientation to support drainability (site dependent)
Applications
- Purified Water (PW) distribution loops
- Water for Injection (WFI) distribution loops
- Pharmaceutical and biotechnology hygienic utilities and process lines
- Drug formulation and high-purity fluid handling systems
Share your media, operating conditions, and whether you need shut-off or regulation, and we will align a hygienic valve selection to your PW / WFI requirements.
