Watson McDaniel TD700S Thermodynamic Steam Trap

The Watson McDaniel TD700S thermodynamic steam trap is commonly used as a drip trap on steam mains and steam supply lines. These traps are used on tracing applications; however, thermostatic traps are normally recommended for this service. Supplied with an integral strainer and optional blowdown valve to protect the trap from contamination. The internal working mechanism of the TD700S can be completely replaced while the trap body remains in line. Ideal for outdoor applications that are subject to freezing and for superheated steam conditions.

HOW IT WORKS
The thermodynamic trap has cyclic on-off operation with a disk that is pushed open by incoming condensate and closes tightly when steam tries to escape.

FEATURES
* Quick Change capsule design for easy in-line repair
* Integral strainer with optional blow-down valve to protect trap from contamination
* High pressure applications up to 600 PSIG
* Hardened stainless steel seat and disc for extended service life even at high pressure
* Single trap will operate over the entire pressure range (4-600 PSIG)
* Unaffected by superheated steam
* Freeze proof when trap is piped in a vertical orientation for complete drainage of condensate
* Weldable body in chrome-moly alloy steel
* Trap will function in any orientation (horizontal preferred)

INSTALLATION
Trap can be installed in any position; however, horizontal is preferred. Installation should include isolation valves.

MAINTENANCE
Complete replacement of capsule assembly can be performed while the steam trap remains in line. For full maintenance details see Installation and Maintenance Manual.
