GEMÜ BB04

The GEMÜ BB04 3 piece metal 2/2-way sanitary ball valve provides hygienic flow isolation for pharmaceutical and biotechnology process applications. The GEMÜ BB04 accommodates nominal sizes from DN 8 to DN 100, regulates operating pressures up to 63 bar, and withstands extreme media temperatures ranging from -10°C to 220°C. Key Performance Capabilities: High Purity Media Integrity: The GEMÜ BB04 integrates a 1.4435 stainless steel alloy body featuring a checked delta ferrite content below 3%, preventing media contamination and lowering long term maintenance costs in critical water treatment and steam generation lines. Standardised Automation Integration: The GEMÜ BB04 incorporates a bare shaft design with an ISO 5211 compliant top flange, guaranteeing precise mechanical alignment during pneumatic or motorised actuator installation to eliminate unplanned process downtime. Zero Dead-Leg Sealing: The GEMÜ BB04 features an optionally cavity-filled PTFE seal mechanism, minimising internal dead spaces to prevent bacterial accumulation and secure complete system decontamination during stringent CIP/SIP sterilisation cycles. Safety & Compliance: Explosive Environment Security: The GEMÜ BB04 integrates an antistatic unit and holds ATEX conformity, preventing electrostatic ignition risks to guarantee facility safety within volatile industrial zones. Pharmaceutical & Food Grade Compliance: The GEMÜ BB04 achieves FDA, USP Class VI, and Regulation (EU) No. 10/2011 conformities, ensuring plant engineers can standardise one sanitary metal ball valve across highly regulated food processing and biotechnology networks. Note: The maximum operational media temperature and pressure ranges depend strictly on the specific ball valve configuration and selected connection standard for the GEMÜ BB04.
