Spirax Sarco launched the TD120M Thermo-dynamic Steam Trap, a product engineered for pressure ratings of up to 3,190 psig that is ideal for draining saturated and superheated steam mains. The steam trap has a maintainable disc and seat, which means it can be serviced in-line—a considerable benefit to customers with welded installations. The trap has a distinct on-off cycle, making it easy to test with many steam trap testing devices. The TD120M includes an integral sintered stainless steel strainer, and the trap does not need a water seal to operate, making it ideal for superheated applications. The standard offering includes alloy steel body and cover construction, chromium steel seat and disc, and three sizes (1/2 inch, 3/4 inch, and 1 inch). (http://www.spiraxsarco.com/us/)
