API 6A Gate Valve Seals integrate with smart wellhead monitoring via pressure sensors across seats. Backup seal activation detects primary failure early. Vee packing stacks handle pulsating flows in pump manifolds. Lantern glands vent packing wear particles. Inconel X-750 garter springs provide consistent load. Seals meet Shell DEP 31.29.00-G5 for global projects. CMM and laser scanning verify as-built dimensions. Robotic assembly ensures contamination-free seals. Proof pressure tests exceed 1.5x rating. Critical for master valves in high-rate gas wells.
