Free Float® Steam Traps for Main LinesFree Float® steam traps for main lines that provide a tight seal even under low condensate load conditions. Steam Traps with Bypass ValveFree Float® steam traps with a built-in bypass valve. Large Capacity Float Steam TrapsLarge capacity steam traps with a maximum discharge capacity of 150 t/h. Clean Steam TrapsFree Float® steam traps for clean steam. Designed to allow complete condensate drainage and easy disassembly for cleaning. Benefits and Features The operation principle of mechanical traps takes advantage of the difference between the specific gravities of condensate and steam. Free Float® steam traps, a TLV invention, are our flagship series of mechanical steam traps. Free Float® steam traps offer the following features: The spherical float provides an infinite number of contact surfaces with the valve seat, ensuring long service life. Air venting feature for improved equipment productivity. Compact design with no levers or hinges. Large tolerance for backpressure allows for problem-free operation even where condensate is recovered. Application Areas Mechanical traps are suitable for use in a variety of applications, including steam main lines, heat exchangers, and insulation applications such as tracers.
