Features

  • Closing time (dynamic response) is a fraction of a second
  • Avoids pressure surges in the pipeline or minimizes them
  • Suitable for high pressure applications (PN50 - 725 psi)
  • No risk of axial disc jamming as the CLASAR® does not have an axial shaft
  • Short face to face, enabling easy installation
  • Perfect disc sealing
  • Excellent erosion resistance of the axial disc
  • Corrosion free axial disc material
  • No maintenance required
  • Suitable for a wide range of applications due to the available materials
