주요 특징
  • Excellent procurement product (No. 2015132) - Rubber seated butterfly valve with metal ring
  • Patent (No. 10-1061095) - Rubber seated butterfly valve with metal ring
  • Patent (No. 10-1456955) - Packing forming method and packing forming apparatus of butterfly valve
  • Prevents the seat joint from being damaged due to the use of an existing adhesive by interpolating and forming the rubber seat annulus rod with the mold integrally.
  • Prevents the rubber seat from being separated by the sudden increases in flow speed and pressure at the time of opening and closing by the valve body where the flow path is formed and the rubber seat annulus where the retention member is interpolated.
  • Has zero leakage according to the standards of the butterfly valve specification (AWWA C504).
  • Features an eccentric structure where the center of the seat is not in alignment with the center of the valve axis, so significantly smaller torque is required in comparison with a concentric structure.
  • Has the structure where the body and the seat are separated from each other so that the durability of the body is semi-permanent.
  • Has the structure that enables the detachment and replacement of the disc seat unit.
