Sampling System for liquids or solids

Design Features

Design Characteristics

  • free of cavity
  • closed system
  • maintenance free – self lubricating
  • pressureless sampling
  • defined representative sample quantity (25ml)
  • piggable
  • no flow interruption
  • simple and foolsafe handling
  • sampling in vacuum possible
  • fugitive emmission resp. clean air act certified (TA – Luft 2002 approval)
  • Directive 2014/68/EU

Functional Principle

Funktionsprinzip-Contiflow-GB

Design variations
• CONTIFLOW = Sampling plug valve with PTFE sleeve
• CONTIFLOW TRF = Sampling plug valve with lined plug (pharmaceutic cip competent)
• CONTIFLOW TRF-A = Sampling plug valve with lined body and plug (pharmaceutic cip competent)

Bottle connection
• PTFE-Adapter: for laboratory bottle with ISO-thread GL 32/45. Application: For less toxic resp. polluted media.
• Clamping Retainer: For fast and easy exchange of laboratory bottle, even for heated version.
• Needle system: closed needle system for laboratory bottle with septum (Butyl and PTFE). Needle System NH and NH-S with diverse internal diameter(2-6 mm). Application for high toxic resp. polluted media for spillnig eliminated an contamination free sampling.

Operating temperatures < -30°C and > 220 °C have to be checked and approved by AZ according to the operating conditions.

Besides the P/T value of the sleeve the limitations of the valve bodies also have to be considered. Please refer to the EN 12516-1 resp. ASME B16.34 in order to choose a proper pressure rating (PN/class). The shown values refer to austenitic stainless steel 1.4408 (A351 Gr. CF8M).

1) For operating temperatures below -10°C low temperature / austenitic steels are required.
2) Sleeve: There are different sleeve materials / compounds available.
