Yarway 731/741 Thermodynamic Piston Steam Trap

Description:

The Yarway Class 600 731/741 Uni Body Piston Trap is an industrial thermodynamic piston steam trap designed for automatic condensate removal in high-pressure and high-temperature steam systems operating up to 600 PSI (40 Bar) and 750°F. It is commonly installed in steam distribution systems, process heating equipment, steam tracing lines, rotating cylinders, jacket kettles, and industrial boiler systems requiring reliable condensate discharge with minimal steam loss. Maintenance personnel and plant operators use this steam trap for repair, retrofit, and replacement of industrial condensate management systems in power generation, petrochemical, refinery, marine, and manufacturing facilities.

Applications:

The Yarway 731/741 Uni Body piston trap is widely used in industrial steam systems such as power plants, refineries, chemical processing facilities, steam tracing systems, and manufacturing plants. It functions as a thermodynamic variable orifice piston steam trap that automatically removes condensate and non-condensable gases while maintaining steam efficiency and protecting steam equipment from condensate buildup and water hammer.
