WT1000/WT1500 Thermostatic Steam Trap

STERILIZERS, DRIP, TRACING: The WT1000 is seal welded and therefore Non-Repairable. It is NOT available with a strainer. This product CANNOT be welded in-line or failure of the Thermal Element may occur. The WT1500 is a repairable version with increased capacity; ideal for sterilizers. These trap is small, light, and has excellent air handling capabilities. The discharging of air on start-up allows steam to enter the system more quickly.

Product Overview
STERILIZERS, DRIP, TRACING: These thermostatic steam traps were specifically designed for drip and tracing applications as well as an air vent for heat exchangers. Like all thermostatic traps, this trap is small, light, and has excellent air handling capabilities. The discharging of air on start-up allows steam to enter the system more quickly.

The WT1000 is seal welded and therefore Non-Repairable. It is NOT available with a strainer. This product can NOT be welded in-line or failure of the Thermal Element may occur. The WT1500 is a repairable version with increased capacity; ideal for sterilizers.

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
How It Works
These trap contains a welded stainless steel thermal element that expands when heated and contracts when cooled to 5°F for WT1000 and 15°F for WT1500 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.

Installation and Maintenance
Trap can be installed in any orientation. This product cannot be welded in-line or failure of the thermal element due to excess heat may occur. The WT1000 steam trap body is seal-welded and therefore non-repairable. If a new trap is required, remove from line and replace. The WT1500 is repairable so in internal seating surfaces and bellow may be accessed for cleaning or repair, if needed. Available in NPT threaded connections only.
Sample Specification
The steam trap shall be of thermostatic type with stainless steel body and stainless steel thermal element.
