High - ultra flow, <3°F (2°C) subcool operation

Three piece, bolted tri-clamp body, very high capacity, dual balanced port, thermostatic sanitary steam trap with integral bypass and vertical or horizontal inlet and/or outlet connections for pure steam SIP and clean utility drain applications in biopharmaceutical and aseptic food & beverage and consumer health & beauty industry applications.

  • Up and downstream process vessel: large vessel, validated SIP drainage applications
  • Up and downstream process vessels: use instead of SIP bypass loop on large vessel; validated SIP drainage from very large vessels
  • Larger filter validated SIP drainage
  • Filling machine or other larger volume validated SIP drainage
  • Large autoclaves
Features & Benefits
  • Significant CAPex savings: the MK934 with it’s integral bypass is designed to eliminate the need for an automated 3-way clean utility bypass valve at bottom of vessel
  • Plant availability increase elimination of the bypass valve expedites heat-up and/or reduces pure steam waste as it disallows escape of pure steam be3fore heat up to 85°C. All of the steam heats the vessel
  • Low subcool operation reduces probability of temperature validation faults and resultant SIP delays
  • For very large process vessels and equipment
  • Self draining when installed with body vertical, regardless of whether inlet/outlet connections are vertical or horizontal
