Often applied on the discharge side of pumps, check valves prevent the system from draining if the pump stops and protect against back flow, which could harm the pump or other equipment.

Key features:

  • Available in sizes: 2″ to 12“.
  • Temperature range: -20°C to 200°C. 
  • Pressure rating: 10 Bar/16 Bar/25 Bar.
  • Low cracking pressure.
