GEMÜ 354

The GEMÜ 354 pneumatically operated 3/2-way globe valve provides precision mixing and distribution for inert gaseous and liquid media. The GEMÜ 354 features a cast bronze body and manages process temperatures from -10°C to 180°C at pressures up to 16 bar within DN 15 to 50 automated systems. Key Performance Capabilities: Process Consolidation: The GEMÜ 354 multi port configuration combines mixing, separating, and aerating functions into a single unit to reduce total component counts and lower system procurement expenses. Maintenance Reduction: A self adjusting gland packing within the GEMÜ 354 provides a reliable valve spindle seal across a long service life to prevent process fluid leakage and unplanned plant downtime. Internal Protection: An integrated wiper ring protects the GEMÜ 354 gland packing against external contamination and debris damage, effectively extending the intervals between required service interventions. Installation Flexibility: The GEMÜ 354 control medium connection rotates through 360° to facilitate simple integration into existing piping layouts and reduce the labour hours required for system assembly. Safety & Compliance: Leakage Prevention: Every GEMÜ 354 valve uses a PTFE seat seal to achieve bubble-tight shut-off in accordance with DIN EN 12266-1 leakage rate A standards for inert air. Defined Control States: The GEMÜ 354 pneumatic actuator is designed for Normally Closed (NC) operation to ensure the valve returns to a secure state during a loss of control pressure. Hazardous Area Support: Ultravalve provides GEMÜ 354 versions compliant with ATEX directives upon request for safe operation within potentially explosive industrial atmospheres. Note: The maximum allowable operating pressure for the GEMÜ 354 decreases as media temperature increases, following the specific pressure/temperature correlation for cast bronze bodies.
