Informatie

WITT non-return valves for reliable protection against dangerous reverse gas flow.
Every non-return valve 100% tested.

Benefits:

  • a spring-loaded non-return valve prevents a reverse flow of gases which could lead to unwanted gas mixtures
  • low pressure drops – using complex valve assembly with low opening pressures, NV800 approx. 6 - 8 mbar
  • no leaks – using of a spring-loaded valve assembly with elastomer sealing
  • stainless steel filter (100 μm) in the gas inlet protects the non-return valve against dirt contamination, extending the service life
  • 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 in accordance with EN 746-2
  • non-return valves are proved in accordance with DIN EN ISO 5175-2. They may also be used as a safety device to protect against flashbacks (proved in accordance with DIN EN ISO 5175-1 point 6.7), which may result from the combustion of natural gas/ LPG with air
  • the maximum ambient / working temperature is 70 °C / 158 °F

Maintenance:

  • annual testing of the non-return valve and body leak tightness is recommended
  • non-return valves are only to be serviced by the manufacturer
