GEMÜ 550

The GEMÜ 550 pneumatically operated 2/2-way angle seat globe valve provides automated flow isolation for gaseous, liquid and viscous media up to 25 bar. The GEMÜ 550 integrates a stainless steel piston actuator and 1.4435 investment casting body to maintain operational integrity in high temperature environments reaching 180°C. Key Performance Capabilities: Vacuum Sealing: The GEMÜ 550 self adjusting gland packing maintains strict spindle sealing under vacuum conditions down to 20 mbar (a), preventing media ingress and eliminating unplanned system downtime. Component Protection: An integrated wiper ring shields the GEMÜ 550 internal gland packing from external particulate contamination, extending the actuator lifecycle and reducing overall replacement frequency. Maintenance Tracking: The optional GEMÜ CONEXO RFID chip enables electronic identification and serialisation, allowing maintenance technicians to execute documented maintenance schedules directly via mobile devices to minimise operational disruptions. Flow Optimisation: The GEMÜ 550 under-seat flow configuration handles incompressible liquid media to actively prevent water hammer, protecting surrounding pipeline infrastructure from catastrophic pressure-wave damage. Safety & Compliance: Food Grade Compliance: The GEMÜ 550 1.4435 investment casting body paired with PTFE seat seals meets FDA, USP Class VI and Regulation (EC) No. 1935/2004 standards, ensuring lawful direct contact within automated food processing lines. Explosion Protection: Specified GEMÜ 550 configurations achieve ATEX (2014/34/EU) conformity, guaranteeing safe automated flow isolation within designated explosive industrial environments. Note: Operational media temperature and pressure ranges depend strictly on the specific seat materials, actuator size and flow direction selected for the GEMÜ 550 valve configuration.
