Mark 94 Series
High flow, <3°F (1.7C °C) subcool operation
Two piece tri-clamp body, balanced port, high flow thermostatic sanitary steam trap with vertical or horizontal inlet and/or outlet connections for pure steam SIP and loop drainage applications in biopharmaceutical and aseptic food & beverage and consumer health & beauty industry applications.
- Up and downstream process vessel medium sized vessel, validated SIP drainage applications
- Up and downstream process tubing: high flow validated SIP tubing drain applications
- Sterile filter, large vent and product filters validated SIP condensate drain applications
- Low subcooling operation reduces probability of SIP delays caused by temperature validation faults
- Easy thermal element (bellows assembly replacement only installs in one direction) error-proof
- New design provides excellent flow rates with low subcooling – improves heat-up drainage
- Self-draining when installed vertically (body outlet side down) – either vertical or horizontal connections
- Solid barstock body with fewer cracks and crevices than competitive designs
- Size: 3/4″, 1″, 1-1/2″ (DN20, DN25, DN40)
- Installation Connection Orientation: Vertical, Horizontal
- Connection Type: ASME, DIN, ISO Tri-Clamp and Tube Weld Ends
- Max. Allowable Pressure Temperature: 145 psig (10 barg); 350°F (177°C)
- Materials of Construction: Wetted body/plug material: ASME SA479 316L (UNS 31606) is standard. EN 10272:2000 GR 14435 is optional. Body gaskets: various, all FDA and USP Class VI
- Nominal Cv (Kv): 4.0 (3,45)
- Surface Finish: Internal: SF1, 20 Ra μin (0,5 μm) standard; SF5, 20 Ra μin (0,5 Ra μm) electropolish or better optional
- Subcooling: Less than 3°F (1.7C °C)

What makes the Mark 94 Series different from other steam traps?
The Mark 94 Series is specifically engineered for high-capacity clean steam applications, offering superior condensate handling capabilities, robust construction, and reliable performance in demanding pharma, biotech and food processing environments.
What does “high capacity” mean for steam traps?
The Mark 94 can handle significantly higher condensate flow rates than standard steam traps in the same size range, making it ideal for large steam systems, heat exchangers, and industrial processes that generate substantial amounts of condensate.
What is “clean steam” and why does it matter?
Clean steam refers to steam that meets pharmaceutical, biotech or food-grade standards – free from contaminants and additives. The Mark 94 is specifically designed with materials and construction that maintain steam purity and prevent contamination.
What if a steam trap is passing steam?
Steam passing could indicate internal wear, improper sizing or sizing conditions exceeding design parameters. Professional inspection and possible service may be needed to restore proper operation.
