Disc and seat oblique cone design turns the compression seal into torque seal, achieves bi-directional seals. Metals and non-metallic compound seal ring combines the rigidity of the metal, the wear-resistance and flexibility of the soft seat, ensures reliable seal and greater performance. Low opening torque value.
