Steam Lock Release - When a trap is installed above the discharge of the process, the trap can be locked due to trapped steam in the piping. To help eliminate this requires an optional steam lock release mechanism.

WT2000 Thermostatic Steam Trap

DRIP, TRACING, PROCESS: The WT2000* thermostatic steam trap is used for drip, tracing, and process applications. Their compact size, all stainless steel construction,excellent air & handling capabilities, and the ability to operate over a wide & pressure range make them a good choice for most applications. They can also be used as an air vent on heat exchangers. Thermostatic traps are far superior to bucket traps and thermodynamic traps in their ability to remove air from the system. The discharging of air on start up allows steam to enter the system more quickly.

* WT2001 refer to 3/16" orifice size and should be used on all drip and tracing applications,WT2003 refer to 5/16" orifice size.

Product Overview
DRIP, TRACING, PROCESS: The WT2000 is a general purpose medium-capacity thermostatic trap that can be used for steam tracing, as a drip trap on steam mains and steam supply lines, as well as for process applications. They are also commonly used as an Air Vent on heat exchangers or at the ends of steam mains. Thermostatic traps are small, light weight, operate over a wide pressure range, and have excellent air handling capabilities. Discharging air at start-up allows steam to quickly enter the system. All stainless steel construction and integral strainer, make the WT2000 an excellent choice for a variety of applications. Trap body is permanently seal welded together and therefore non-repairable. Contains an extremely strong and rugged precision welded Stainless Steel thermal element which is highly resistant to waterhammer.
Features
• Thermostatic traps are excellent at discharging air, which allows steam to enter quickly; extremely important during start-up
• Freeze-proof when trap is installed in a vertical orientation allowing for complete condensate drainage
• Welded stainless steel thermal element resists shock from waterhammer
• Body is produced from stainless steel investment casting
• Hardened stainless steel seat for extended service life
• Integral strainer to protect trap from contamination
• Will operate at steam pressures up to 650 PSIG
How It Works
This 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.
Selection / Sizing / Capacities
Two orifice sizes are available: The 3/16” orifice should be used on all drip and tracing applications as well as small process applications with lower condensate loads. The 5/16” orifice is available to be used on process applications if additional capacity is required. Select working pressure; follow column down to correct capacity (lbs/hr) block.

Example:
Application: 1827 lbs/hr at 100 PSIG working inlet pressure
Size/Model: WT2001-12-N, 1/2” NPT, 3/16” orifice


Note:  3/16" orifice should be used on all drip and tracing applications.

Options
• Special Bellows Option; available upon request:
   • Fail-closed Bellows (standard bellows fails in open position)
   • 43°F Sub-cool Bellows (Note: Standard bellows are designed for approximately 5°F sub-cool temperature)

SLR = Steam lock release

• Standard models contain a non-cleanable strainer screen. Also available without screen where it is desireable to flush dirt and scale thru the trap. Recommend WT2003 with larger orifice if used   without strainer.

Installation and Maintenance
Trap can be installed in any position. The WT2000 steam trap body is seal-welded and therefore non-repairable. If a new trap is required, remove from line and replace. Cannot be welded in-line or failure of the thermal element may occur. Available in NPT threaded connections only.
Sample Specification
Steam trap shall be of thermostatic type with stainless steel body, thermal element, internal screen, and hardened valve and seat.
