CLASAR CHECK VALVE DN 80 to 1800 - Series B6 10

CLASAR is a concentric discs check valve, ensuring the protection of the pumps against flow inversion.
Description

  • Anticipated closing creating no water hammer in pipelines.
  • Silent.
  • Damping of the check valve strock thanks to the elasticity of the disc made of polyurethane.
  • Compactness.
  • Extensive ranges of working pressures and diameters.
  • Body and disc hydraulically profiled optimising the passing of the flow.
  • Wafer body from DN 80 to 500 and flanged body from DN 600 to 1800.
  • Standard stainless steel spring.
