Traps
The Mark 93JR is an ultra compact, balanced port,
thermostatic steam trap designed specifically for use in
validated clean steam systems for low to medium con-
densate flows. The sanitary design follows ASME BPE
guidelines including a 20Ra
µin internal finish, self-
draining design, and all relevant materials, marking
and documentation.
The MK93JR has been specifically designed to provide
low to medium flow rates at low subcooling levels. In
lab testing, the MK93JR consistently exhibited excel-
lent flow rates at subcooling levels of less than 3°F or
less (<1,7°C). Note: Low subcooling operation insures
that condensate is less likely to back up and wet (cool)
the upstream validated temperature sensor.
How They Work
During start-up, the bellows element is contracted and
fully open to discharge all non-condensable gas and
condensate. The heat of entering steam causes the
element to expand, closing the valve. As condensate
accumulates in the body, the element cools, causing
the bellows/stem tip to retract allowing condensate to
drain.
Features
• Compact design, small lay-in length - ideal for
compact installations like process skids
• The only compact sanitary trap with a Tri-clamp
body to facilitate quick bellows assembly
change out
• Low subcooling operation reduces probability
of temperature validation faults and resultant SIP
delays
• All 316L stainless steel housing and internals
• Polished components – body interior is mechani-
cally polished to ASME BPE SF1, 20 μin (0,5 Ra μm)
mechanical polish. External body is mechanically
polished to 40 Ra μin (1 Ra μm).
• Sanitary clamp ends standard, other ends (tube
weld, threaded, ISO/DIN) available upon request
• Self draining when installed vertically (outlet side
down)
• FDA and USP Class VI TFE-VIT gasket standard
• Option for electropolished body
• Standard Steriflow Valve warranty applies
Applications
• Typical application is for SIP clean conden-
sate drainage on validated bioprocess skid
systems. In this environment, the compact
size makes it ideal for:
- Fermenters, Bioreactors, Separation,
Filtration and Purification skids and
formulation and filling equipment
- May also be used for clean steam
distribution line drainage
