Quattroflow 5k Max. Flow Rate 6,000 lph

  • Increased max. flow rate of 6,000 lph with most drives
  • Clean-In-Place/Steaming-In-Place (CIP/SIP) and autoclavability
  • Self-draining design to minimize non-recoverable product
  • Enhanced venting to reduce the minimum flow rate required to remove entrapped air during priming
  • Patented valve plate design to achieve self-draining and venting
  • Up to 120:1 turndown ratio
  • Improved linear flow performance
  • High flow stability across entire flow range
