GEMÜ B20

The GEMÜ B20 2 piece metal 2/2-way manual ball valve provides secure flow isolation for inert, corrosive and gaseous media applications. The GEMÜ B20 accommodates nominal sizes from 1/4" (DN 8) to 2 1/2" (DN 65), regulates operating pressures up to 63 bar, and withstands media temperatures ranging from -20°C to 180°C. Key Performance Capabilities: Optimised System Footprint: The GEMÜ B20 uses a compact 2 piece investment casting body with a standardised DIN 3202 M3 overall length, ensuring seamless integration into tight pipework environments while maintaining a high flow rate. Secure Mechanical Actuation: The GEMÜ B20 integrates a plastic-sleeved hand lever featuring a built-in locking device, securing mechanical flow regulation to prevent accidental operation and eliminate unplanned process downtime. Targeted Sealing Integrity: The GEMÜ B20 features a blow-out proof shaft combined with PTFE seat seals, preventing chemical degradation and media leakage to lower long term component replacement costs in aggressive fluid systems. Safety & Compliance: Explosive Environment Security: The GEMÜ B20 integrates an antistatic unit and supports ATEX conformity, preventing electrostatic ignition risks to guarantee facility safety within volatile industrial zones. Sanitary & Oxygen Compliance: The GEMÜ B20 achieves DVGW Gas, FDA, Regulation (EC) No. 1935/2004 and Functional safety conformities alongside a specialised oxygen version, ensuring plant engineers standardise one metal valve across sanitary and critical gas distribution networks. Note: The maximum operational media temperature and pressure ranges depend strictly on the specific ball valve configuration selected for the GEMÜ B20.
