Low Emission and Anti-blowout Stem Design
Packing made by pre-compressed flexible graphite rings, the roughness of stuffing box and stem is well controlled to ensure lower torque and better sealing. The live loaded gland flange is available to adjust the compression of the packing seal. The space ring and gland design can prevent the stem to be blow-out.
