GEMÜ 654

The GEMÜ 654 BioStar 2/2-way manual metal diaphragm valve provides sterile flow isolation for critical pharmaceutical and high purity industrial processing lines. The GEMÜ 654 accommodates nominal sizes from DN 4 to DN 100, regulates operating pressures up to 10 bar, and handles media temperatures ranging from -30°C to 130°C. Key Performance Capabilities: Aseptic Process Integration: The GEMÜ 654 BioStar delivers complete CIP/SIP (Cleaning and Sterilisation in Place) capability and withstands intermittent autoclave sterilisation up to 150°C, preventing biological contamination to guarantee sterile product yields within aseptic fluid networks. Mechanical Flow Precision: The GEMÜ 654 BioStar integrates an opening and closing stroke limiter alongside a standard optical position indicator, enabling plant engineers to secure minimum flow regulation while preventing diaphragm compression damage to extend operational service life. Secure Mechanical Actuation: The GEMÜ 654 BioStar features an electropolished stainless steel handwheel supporting optional electric or mechanical locking mechanisms, securing manual flow parameters to prevent accidental operation and eliminate unplanned process downtime during pipeline interventions. Positional Feedback Security: The GEMÜ 654 BioStar supports configurable proximity switches, providing plant engineers with precise mechanical position feedback to drastically reduce diagnostic downtime across complex pharmaceutical processing skids. Safety & Compliance: High Purity Environmental Security: The GEMÜ 654 BioStar holds FDA, USP Class VI and 3A conformities, preventing biological contamination to guarantee process safety within aseptic biopharmaceutical production zones. Emissions & Specialised Compliance: The GEMÜ 654 BioStar achieves TA Luft and Functional safety conformities alongside an optional ATEX-rated electromagnetic locking device, ensuring plant engineers can standardise manual fluid control across explosive and emission controlled networks. Note: The maximum operational media temperature and pressure ranges depend strictly on the specific diaphragm material and selected body configuration for the GEMÜ 654 BioStar.
