Thermodynamic steam traps combine reliability, simplicity and efficiency of operation. With just one moving part - a hardened stainless steel disc - they give a blast discharge with clean, tight shut-off. Able to withstand superheat, waterhammer, corrosive condensate, freezing and vibration the TD trap is the first choice for removal of condensate from steam distribution systems. Range: 3/8'' to 1''; up to 3,625 psig; carbon steel, stainless steel and alloy steel; capacities up to 4,700 lb/h.
