DELCO TD Series Threaded Thermodynamic Disc Steam Trap, BSP/NPT, DN15–DN25, PN16/PN25

DELCO TD Series threaded thermodynamic disc steam trap uses a disc-type thermodynamic principle to discharge condensate in cycles and close tightly when steam arrives, offering a compact, rugged option for steam mains drainage and many tracing points. It supports BSP or NPT threaded connections for quick installation on small-bore lines and skid piping where flanged space is limited.

Features

Compact threaded disc trap for steam lines—simple, durable, and easy to install on small-bore piping.

✅Simple disc mechanism: One moving disc opens to discharge condensate and closes in the presence of steam, giving dependable cyclic drainage with minimal parts.

✅Ideal for small-bore installations: BSP/NPT threaded ends suit DN15–DN25 lines, making it easy to retrofit on tracers and compact steam skids.

✅Rugged for distribution service: Thermodynamic traps are widely used on steam distribution drains due to their compactness and durability.

✅Broad pressure usability: A single thermodynamic disc design can cover a wide pressure range, reducing spares complexity.

✅Cleaner steam and easier maintenance: Pairing with a (manual ball valve) for quick isolation and a (Y-strainer) upstream to reduce debris helps keep the trap working reliably and simplifies servicing.
