Low Emission and Anti-Blowout Stem Design

The packing is made from pre-compressed flexible graphite rings, with precisely controlled stem and stuffing box surface roughness to ensure lower torque and enhanced sealing performance. A live-loaded gland flange allows for easy adjustment of packing compression. The space ring and gland design effectively prevent stem blowout, ensuring safety and reliability.
