FAQs for Check Valves (non-return valves)

Check valves are essential components that prevent fluid or gas from flowing in the wrong direction. They offer numerous benefits, including:

  • Safeguarding equipment from damage caused by backflow.
  • Maintaining fluid purity by preventing the mixing of different materials.
  • Preventing pipe system failures and ensuring uninterrupted operation.
  • Ensuring consistent pipe system pressure for optimal performance.
  • Protecting systems from damage caused by debris and contaminants.

A single check valve offers protection against backflow in water that has undergone changes in appearance, taste, odour, or temperature but remains safe for consumption and poses no health risks. A common application for single check valves is in systems where hot and cold water supplies are mixed.

A double check valve, essentially two single check valves working in tandem, provides a more reliable and secure solution for preventing contamination through backflow. The additional valve enhances the seal, creating a stronger barrier.

Non-return valves are often used in applications where preventing backflow is beneficial but not strictly necessary.

Unlike check valves, non-return valves typically aren't designed for long-term reliability, use with drinking water, or performance under stress. Check valves on the other hand, undergo rigorous testing to ensure they meet these higher standards.
