Benefits and Features

Improved Heating Efficiency (J10/JH15): FLOATDYNAMIC® construction includes a larger valve opening, making it possible to discharge large amounts of condensate from steam-heating equipment that uses greater amounts of steam than average.; The Free Float® responds with great sensitivity to the flow of condensate, rapidly initiating condensate discharge as soon as condensate enters.
Improved Heating Efficiency (JL/JLH): Float and lever construction with a double-seated valve. Discharges large amounts of condensate from steam heating equipment that uses greater amounts of steam than average.; 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.

Application Areas

Suitable for processes that use large quantities of steam in continuous operation.

Main Applications: Reboilers, large heat exchangers.

1 Depending on the operation condition, the indicated equipment may be subject to "stall" (see 3 below). In such cases, GT Series PowerTraps are required. GT Series PowerTraps are steam traps that feature a pump function.				GT Series	PowerTraps

*2 Operating pressures vary between different models of the same series. For details please refer to individual Specification Data Sheets (SDS).

*3 "Stall" is a phenomenon where the internal pressure of an equipment falls below the back pressure on the outlet side, resulting in back-up of condensate that cannot be discharged by conventional steam traps. "Stall" can cause damage such as uneven/incomplete product heating, corrosion and waterhammer.
