Mark 94 Series
High Flow Sanitary Steam Traps
The Mark 94 is a thermostatic steam trap designed
specifically for use in high capacity clean steam
systems where sanitary conditions must be maintained.
It features a 20 Ra internal finish, and a self-draining
design, to minimize the possibility of medium entrapment and bacterial growth.
The Mark 94 has been designed to provide high condensate flow rates during SIP heat up, allowing vessels and other process equipment to reach validation
temperature in minimum time.
The proprietary fill, bellows and orifice design minimize
the subcooling required to open the trap during SIP
temperature hol, insuring fast drainage under lower
load conditions to help insure against low temperature
faults.
The Mark 94 is designed for use up to 50 psig (3,5 bar)
inlet pressure.
Sanitary Valves Mark 94 Sanitary Steam Traps
OperatiOn
During SIP Heatup, the bellows assembly is fully open
to discharge all air, non-condensate gases and cool
condensate. The heat of the 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 flow.
Features
• Body and solid internal components constructed of
ASTM A479 316L
• Polished components – body interior and exterior
are mechanically polished to 20 Ra finish
• Sanitary clamp ends standard, other ends (tube
weld, threaded, ISO/DIN) available upon request
• Self draining when installed vertically (outlet side
down)
• New design provides excellent flow rates with low
subcooling during heat up and temperature hold
period
• FDA, USP Class VI gasket standard
• Horizontal connections available
applicatiOns
• Typical applications are: fermentors,
bioreactors, sterilizers/autoclaves
• Condensate drainage from large tube
clean steam distribution loops
• Condensate drainage from large scale
process systems – fermenters, bioreactors,
holding vessels, separators, chromatography vessels, etc.
