High Purity Sampling Valves

Ultra Pure PVDF Sampling Valve

Water sampling is a vital element in maintaining an ultra pure water system. For the most critical applications in semiconductor manufacturing, low quality water has a direct and measurable impact on product success. Even worse are false positives and system downtime.

Asahi/America has developed this welding technology and sampling product to provide the cleanest possible external measurement. Eliminate doubt in your design, build sample locations into your system at easy-to-reach, recirculating locations.

  • Reduced dead leg reduces bacteria propagation
  • IR welded for clean, ultra pure samples
  • Proprietary IR technology based on SP series of equipment
  • Full pressure rating at 68°F
