Spirax Sarco thermodynamic steam traps combine safe and reliable operation, simple construction and efficient condensate removal, with maximum operating pressures up to 250 barg. The design uses a single moving part, a hardened stainless steel disc, to provide long service life. It closes quickly and tightly to minimise leakage, and it tolerates superheat, waterhammer, freezing conditions and corrosive condensate well. The distinctive closing click helps with operational checks, the traps can work in any orientation, and a broad selection of threaded, flanged and weld-end versions is available. That combination of compact size, robustness and wide pressure capability makes them especially common on steam mains, tracing and other duties where disc trap behaviour is a strong fit. They remain a practical route wherever users want one of the simplest trap mechanisms available without giving up broad operating capability.
