    Free Float® Steam Traps (Low Pressure)

    JX Series/FJ32 Series/SJ Series

    Free Float® Steam Traps for Process Use

    JX series steam traps can be installed on various types of equipment that uses steam as a heat source. The series covers a wide range of condensate loads, from the 100’s of kg/h to several 10’s of tons/h, making this TLV's most widely used series of steam traps.

    In addition to offering compact size, continuous discharge of condensate, and large condensate discharge capacities, these steam traps are equipped with an X-element air-vent that provides a powerful automatic blow-out function. All these qualities gathered in one trap make the JX series ideal for steam-using equipment.

    Benefits and Features

    Improved Efficiency of Heating Equipment

    The Free Float® rises and sinks as the flow of condensate fluctuates, opening the valve to discharge condensate and closing off the valve when steam enters.
    The built-in X-element (model names including 'X') functions as an air vent, discharging both cool and hot air. As a result, the steam chamber inside the equipment contains only steam, which allows the equipment to achieve optimized heating performance.

    Long Service Life, Excellent Durability

    The spherical Free Float® rotates during operation, allowing any point on its surface to act as the valve seal and thus ensuring long service life.
    Stainless steel models also available for increased durability.

    Protects Equipment

    'Fail Open' Design: The X-element is designed to fail open so that the valve remains open even in the event of failure.

    Application Areas

    Especially suitable for steam processes.

    • Heat exchangers, reactor kettles, vulcanizing pans, jacketed kettles, roller heat exchangers, cylinder dryers, etc.
