● 2CW-CW dual seal of API682 arrangement 2.

● The inner side adopts high-pressure sealing, the entire seal size is compact.

● The medium does not leak into the atmosphere. Usually, small inner leakage should be

　discharged into the flare system.

● This type of seal is suitable for mediums under high pressure conditions, such as light

　hydrocarbons, aromatics, ethene, propylene etc.

● Multi-springs

● Rotary type

● Convex lug drive

● High pressure seal in Process side
