Low Emission and Anti-Blowout Stem Design
Featuring pre-compressed flexible graphite rings, the stem packing ensures lower torque and enhanced sealing performance, with the roughness of the stem and stuffing box precisely controlled. The live-loaded gland flange allows for convenient adjustment of the packing seal compression, ensuring optimal sealing. Additionally, the space ring and gland design provide robust protection against stem blowout, guaranteeing reliable operation even in high-pressure environments.
