WITT non-return valves for reliable protection against dangerous reverse gas flow. Flow-optimised valve system causes very low pressure drop at minimal noise emission. Every non-return valve 100% tested.


  • a spring loaded non-return valve prevents back feeding of gases which could lead to unwanted gas mixtures
  • low pressure drop – using complex valve assembly with low opening pressures (ca. 5 mbar)
  • stainless steel filter (100 μm) in the gas inlet protects the non-return valve against dirt contamination, extending the service life
  • flow-optimised valve system for:

    - ultra low pressure drop
    - minimal noise emission

  • no leaks – using of a spring loaded valve assembly with elastomer sealing
  • in accordance to DIN EN ISO 5175-2
  • available in brass or stainless steel
  • diverse applications – useful for many technical gases
  • reduce installation costs – the spring loaded valve is not affected by gravity and may be installed in any orientation

Operation / Usage

  • non-return valves are used to protect equipment and pipelines against dangerous reverse gas flow. Use is possible for applications according to EN 746-2
  • WITT non-return valves may be mounted in any position / orientation
  • in ambient temperatures above -20 °C / 68 °F and below +70 °C / 158 °F


  • annual testing of the non-return valve and body leak tightness is recommended
  • WITT is happy to supply special test equipment
  • non-return valves are only to be serviced by the manufacturer

Company certified according to ISO 9001
