Thermostatic Steam Traps

Steam Traps — New & Used

Steam traps automatically remove condensate and non-condensable gases from steam systems while keeping live steam in the line—protecting equipment, improving energy efficiency, and preventing water hammer. Offered in mechanical (float & thermostatic), thermodynamic (disc), and thermostatic (balanced-pressure/bimetal) designs, traps are available in cast iron, steel, and stainless with NPT and flanged ends to cover a wide range of pressures, temperatures, and condensate loads.
