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 entrap-

ment and bacterial growth.

The Mark 94 has been designed to provide high con-

densate ﬂow rates during SIP heat up, allowing ves-

sels 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.

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, chromatogra-

phy vessels, etc.
