The Mark 93 is a balanced port, thermostatic steam
trap designed specifically for use in validated clean
steam systems. The sanitary design follows ASME BPE
guidelines including a 20Ra
µin internal finish, self-
draining design, and all relevant materials, marking
and documentation guidelines.
The MK93 has been specifically designed to provide
higher flow rates at low pressures and low subcooling
levels. In lab testing, the MK93 consistently exhib-
ited excellent flow rates at subcooling levels of less
than 3°F or less (<1,7°C). Note: Low subcooling op-
eration insures that condensate won’t back up and wet
(cool) the upstream validated temperature sensor.
There are two base designs within the MK93 product
range: the standard MK93 – good for inlet pressures
(P1) up to 50 psi (3,4 bar), and the MK93 Option “P”
for inlet pressures ranging from 45 – 90 psi (3,1 – 6,2
bar). Both designs are rated to 90 psi (6,2 bar) operat-
ing pressure but are recommended for use within the
specified inlet pressure ratings.
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.
