Traps
The Mark 93TH is a balanced port, thermostatic steam
trap designed for use in validated clean steam systems
that use threaded tube fittings or threaded tubing
adapters for connections. The sanitary design includes
a 20Ra
µin internal finish, self-draining design, and a
compact size.
The MK93TH is designed with the same bellows as our
MK93, and will therefore allow higher flow rates than
competitive designs. Note: Low subcooling operation
insures that condensate won’t back up and wet (cool)
the upstream validation temperature sensor.
There are two base designs within the MK93TH
product range: the standard MK93TH – good for inlet
pressures (P1) up to 50 psi (3,4 bar), and the MK93TH
Option “P” for the higher inlet pressure associated with
clean steam distribution drainage, or any application
with pressure ranging from 45 – 90 psi (3,1 – 6,2 bar).
Both designs are rated to 90 psi (6,2 bar) operating
pressure but are recommended for use within the
specified inlet pressure ratings.
Mark 93TH Operation
During heat-up, the bellows element is contracted and
fully open to discharge all non-condensable gas and
condensate. As recorded temperature rises, not as
much condensate is formed,and the temperature of
the condensate rises as the level in the upstream tub-
ing falls. This causes the bellows 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 size makes it the ideal sanitary trap for
tight fitting process skid applications
• Competitive lay-in dimensions allow in kind
replacement of troublesome existing installations
• Low subcooling operation reduces probability
of temperature validation faults and resultant SIP
delays
• Higher capacities and lower subcooling than com-
petitive designs allows faster heat-up.
• All 316L stainless steel housing and
internals
• Polished components – body interior is
mechanically polished to 20Ra finish
• Self draining when installed vertically
(outlet side down)
• Option for electropolished body
Applications
• Typical applications are: temperature
validated sterilization drainage of fermen-
ters, bioreactors, separation and filtration
equipment, lyophilizers, autoclaves,
process piping equipment and steam
barriers.
• Condensate drainage from clean steam
distribution lines
