Product Description

Check Valves are automatic shut-off valves that are commonly used for preventing back flow or drainage in a piping system. 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.

Wafer Type Single Disc Swing Check Valves are designed for installation in flanged piping systems, between two flanges. Valves may be installed in vertical or horizontal piping.

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.
  • Space saving design.
