TD900S - High Pressure Repairable In-Line

DRIP: The TD900S Thermodynamic steam trap is primarily used as a drip trap on high pressure steam mains and steam supply lines when a repairable trap type is desired. Ideal for outdoor applications that are subject to freezing and for super heated steam conditions. The TD900LS is recommended for pressure over 300 PSI.

DRIP: TD900S model steam traps, capable of handling pressures up to 900 PSIG, are used in drip applications such as draining condensate from steam mains and steam supply lines. The complete internal working mechanism can be replaced while the trap body remains connected in-line. All models contain an integral strainer for protection against dirt and scale. These traps are suitable for outdoor applications that are subject to freezing as well as superheated steam conditions.
