Options & Features (See Specification Sheet For Full List):
TS25B Series Radiator Steam Trap
Radiator Steam Traps are predominantly used in the HVAC industry because the quick-disconnect right angle connection is found on most radiator installations. Their excellent air handling capabilities, compact size, and economical cost make them a great choice for air vents on heat exchangers or for steam trap applications on OEM equipment.
The TS25B Series Radiator Trap with Straight-thru (in-line) connection are Thermostatic Steam Traps that were specifically designed for removing condensate and air from 2-pipe steam heating systems. The bodies are made from a high-quality brass forging and can be fully repaired while the product remains in-line by removing the cap and easily replacing the seat and thermal element. It is available in 1/2" & 3/4" NPT connections with pressure ranges: 25 PSIG.
TA & TS type steam traps are predominantly used in the HVAC industry. They are referred to as radiator traps because the quick-disconnect right angle connection of the TA Type is found on most steam radiator installations. The TS Type offers a straight-through connection alternative. TA and TS Series radiator traps were designed specifically for removing condensate and air from 2-pipe steam heating systems. Their excellent air-handling capabilities, compact size, and economical cost make them a great choice for air vents on heat exchangers or for steam trap applications on OEM equipment. Contains an extremely strong and rugged precision-welded Stainless Steel thermal element which is highly resistant to waterhammer.
How It Works
This 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
Select differential pressure; follow column down to correct capacity (lbs/hr) block.
Example:
- Application: 2100 lbs/hr at 40 PSI differential pressure
- Size/Model: 3/4" TA125
Installation & Maintenance
Trap can be installed in any orientation. The bodies are made from a high-quality brass forging and are easily repairable while the steam trap remains in-line by removing the cap and replacing the seat and thermal element. Repair kit includes thermal element, seat and gasket.
