Butterfly Swing Check Valve - Type C09.5

  • Possibility of installation into vertical, horizontal or inclined pipings
  • Fabricated design, which allows us flexibility (no castings)
  • Maintenance free and long service life
  • Minimization of water hammer

Add to compare

The Type C09.5 is a self-acting, fast-closing butterfly swing check valve designed to prevent the reverse flow of working media in pipelines, particularly for pumps and fans. It is characterized by an eccentrically embedded disc that rotates inside a flanged, fabricated body, with a lever and counterweight often attached to the shaft.

Use Cases

  • Prevention of backflow in pumps, fans, and pipeline systems
  • Suitable for large-diameter piping systems requiring automatic non-return function
  • Industrial systems handling water, air, steam, and non-aggressive fluids/gases

Capabilities

  • Prevents reverse flow in pipelines (non-return functionality)
  • Operates as a self-acting, automatic, quick-closing valve
  • Handles multiple media: water, air, steam, non-aggressive liquids and gases
  • Supports wide size range (DN 100–1600) and high pressure classes (PN 6–100)
  • Allows flexible installation orientations
  • Provides low pressure loss and reduced water hammer effects
