  • Manual or pressure operated aseptic valve, designed for the bioprocessing industry.
  • The diaphragm separates the operator from the fluid and ensures safety and quality of the final product.
  • Forged body complies with stainless steel 316L, 1.4435 sulfur controlled to ASME BPE standards, and contain under 0.5% of ferrite.
  • Resistant to standard washroom protocols, this valve is the compact, autoclavable solution for Pharmaceutical / Bioprocessing applications.
  • Modular compressor designed for quick changeover between PTFE and elastomer diaphragm.
  • Suite for severe duty applications, such as SIP and high cycle applications.
  • Autoclavable (steam at 125°C for 25 minutes).
  • Designed for sampling and other low flow, high value processes like bioreactors, chromatography systems, and filtration skids.
