Major Features
  • It ensures zero leakage according to the standards of butterfly valve specification (AWWA C504)
  • It has the structure with the body and the body seat separated from each other so that the durability of the body is semi-permanent.
  • Its structure enables the replacement of the disc seat unit.
  • It is easy to operate it under heavy load conditions.
  • It has the 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 to the concentric structure.
