● Pressure：0~6.0 MPa

● Temperature： -40~260℃

● Speed：≤25m/s

√ Applied in high pressure medium, like, light hydrocarbon, aromatic hydrocarbon, ethylene, propylene ,etc.

√ Prevent medium leaking into the atmospheric, usually micro leakage inside should be discharged into the flare system;

√ High pressure seal in process side, the unique design of the primary ring is beneficial to reduce the deformation of seal faces and increase the heat dissipation area;

√ Short axial dimension and compact designs

● Double seal with tandem arrangement

● High pressure seals in process side

● multiple springs, rotary

● Torque transmitted by lugs

● Dent drive

√ Refining & petrochemical

√ Coal chemical

√ Chemical

√ General industry

● Process side:API682 PLAN 11, 21, 32,

● Between seals:API682 PLAN 52, 55
