Clean Steam Traps — Thermostatic FDA500 Series

Sanitary Steam Traps are designed to offer free flow-through internal passages by incorporating very smooth internal finishes (20–25 Ra). For periodic passivation and sanitation of the system, these traps offer a tri-clamp connection on the body to allow for removal of the thermal element.

Clean Steam Traps are steam traps designed for similar functionality as the sanitary traps, but do not offer the same level of surface finish.

Applications

The FDA500 Series Thermostatic Steam Traps are used on clean steam applications as drip traps on piping runs as well as drainage for CIP (Clean in Place)/SIP (Sanitize in Place) systems and various process vessels.

Operating Principle

The trap contains a welded 316L stainless steel thermal element that expands when heated and contracts when cooled. When air and condensate are present, the trap is in the open discharge position. When steam reaches the trap, the element expands, closing the trap tightly. All wetted parts are 316L stainless steel.

Surface Finish

• Internal body: Electro-polish finish of 20–25 microinches Ra
• External body: Electro-polish finish of 25–32 microinches Ra
