GEMÜ 514

The GEMÜ 514 pneumatically operated 2/2-way angle seat globe valve provides automated flow isolation for corrosive, inert, gaseous and liquid media up to 25 bar. The GEMÜ 514 integrates an aluminium piston actuator and self adjusting PTFE gland packing to maintain operational integrity in high temperature environments reaching 180°C. Key Performance Capabilities: Flow Optimisation: The GEMÜ 514 angle seat design delivers flow rates up to 152.1 gpm for DN 80 configurations to reduce system pressure drops and lower long term pumping energy costs. Vacuum Sealing: The GEMÜ 514 self adjusting gland packing maintains strict spindle sealing under vacuum conditions up to 0.59 inHg absolute, preventing media ingress and eliminating unplanned system downtime. Component Protection: An integrated wiper ring shields the GEMÜ 514 internal gland packing from external particulate contamination, extending the actuator lifecycle and reducing overall replacement frequency. Installation Integration: The GEMÜ 514 control medium connection provides 360 degree adjustment, allowing operators to configure the actuator within restricted pipework layouts to minimise initial installation labour costs. Safety & Compliance: Food Grade Compliance: Specified GEMÜ 514 stainless steel body variants paired with PTFE seat seals meet Regulation (EC) No. 1935/2004 standards, ensuring lawful direct contact within automated food and beverage processing lines. Leakage Certification: The GEMÜ 514 internal PTFE seat seals achieve a Leakage Rate A classification under DIN EN 12266-1 P12 air testing procedures, guaranteeing strict process media isolation. Note: Operational media temperature ranges depend strictly on the specific seat and seal materials selected for the valve configuration.
