  • emisión mínima de ruido

 

Información

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.

ULTRA 12 is based on ULTRA 10 and is customised according to the requirements of the customer - ideal for special requirements. A modular system which allows flexible material combinations for housing and sealings.

 

Combination possibilities

  • housing available in brass, stainless steel or aluminium
  • sealings of NBR, CR, FKM, EPDM, FFKM for example
  • with or without dirt filter in gas inlet

 

Benefits

  • precisely tailored design for special requirements. For example corrosive environments, acetylene, ultra-lightweight construction, temperatures above 70 °C / 158 °F
  • 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 (approx. 4 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, stainless steel or aluminium
  • 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

 

Maintenance

  • 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
