Description
The Watson McDaniel WT1000-12-N Thermostatic Steam Trap is a low capacity thermostatic trap ideally sized for steam tracing. Thermostatic traps are small, light weight and have excellent air discharging capabilities. Discharging air at start-up allows steam to quickly enter the system. Trap body is permanently seal welded together and therefore non-repairable. This steam trap contains an extremely strong and rugged precision welded Stainless Steel thermal element. Its small discharge orifice, which makes it an optimal size trap for both drip and tracing applications, is susceptible to clogging depending on system conditions, therefore, a separate strainer should be installed.
While operating, the thermostatic trap contains a welded stainless steel thermal element that expands when heated and contracts when cooled to 5?F below saturated steam temperature. When air or sub-cooled condensate are present, the trap is in the open discharge position. When steam reaches the trap, the element expands and closes off tightly.
WT1000 Features:
- Excellent at discharging air which allows steam to enter system quickly; extremely important during start-up.
- Welded stainless steel thermal element resists shock from water hammer.
- Freeze-proof when trap is installed in a vertical orientation allowing for complete condensate drainage.
- Stainless steel Barstock body.
- In the unlikely event of bellows failure; trap discharge remains open.

WT1000-12-N Installation:
This trap can be installed in any orientation. The WT1000 steam trap body is seal-welded and therefore non-repairable. If a new trap is required, remove from line and replace. This product cannot be welded in-line or failure of the thermal element due to excess heat may occur. Available in NPT threaded connections only.
