High - ultra flow, <3°F (1.7°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 before 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
  • Size: 1″, 1-1/2″, 2″ (DN25, DN40, DN50)
  • Installation Connection Orientation: Vertical, Horizontal
  • Connection Type: ASME, DIN, ISO Tri-Clamp and Tube Weld Ends
  • Max. Allowable Pressure/Temperature: 145 psig (10 barg); 350°F (177°C)
  • Maximum Operating Pressure: 50 psi (3,4 bar)
  • Materials of Construction: Wetted body/plug material: ASTM SA479 316L (UNS 31603) is standard, EN 10272:2000 GR 1.4435 is optional.  Body gaskets: various, FDA and USP Class VI
  • Nominal Cv (Kv): 5.7 (4,93)
  • Surface Finish: Internal: SF1, 20 Ra μin (0,5 μm) standard; SF5, 20 μin (0,5 Ra μm) electropolish or better optional
  • Subcooling: Less than 3°F (1.7°C)
