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.

WT2500 Thermostatic Steam Trap

DRIP, TRACING, PROCESS: The WT2500* thermostatic steam trap is used for drip, tracing and process applications. Their compact size,excellent air handling capability and wide operating pressure range make them a great choice for most applications. Thermostatic traps are far superior to bucket traps and thermodynamic disc traps in their ability to remove air from the system.

WT2501 refer to 3/16" orifice size, WT2503 refer to 5/16" orifice size.

Product Overview
DRIP, TRACING, PROCESS: The WT2500 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. All internal working components can be replaced while the  trap body remains in-line. Like all thermostatic traps, they 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. The WT2500 is an excellent choice for a variety of applications. Contains an extremely strong and rugged precision welded Stainless Steel thermal element which is highly resistant to waterhammer.
Features
• The thermal element and seat can be easily removed and replaced in minutes with the trap body still in-line
• Operates at steam pressures up to 250 PSIG
• Thermostatic traps have excellent air handling capability
• 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
• Hardened stainless steel seat for extended service life
How It Works
The thermostatic trap contains a welded stainless steel thermal element that expands when heated and contracts when cooled. When air and  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).

Example:
Application: 1827 lbs/hr at 100 PSIG working inlet pressure
Size/Model: WT2501-12-N, 1/2” NPT, 3/16” orifice.

Installation and Maintenance
Trap can be installed in any orientation. All internal working components are extremely easy to replace and can be performed while the trap body  remains in line by removing the four-bolt cover. Repair kit includes ALL parts to fully rebuild the steam trap including thermal element, seat and gasket.
Sample Specification
The steam trap shall be of a thermostatic type with cast iron body and stainless steel thermal element. Trap must be in-line repairable with a  bolt-on type cover that is sealed with a spiral wound Stainless Steel AISI 316 gasket. Valve and seat to be hardened stainless steel.
