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.; The built-in bimetal (model names including 'B') functions as an air vent, discharging initial cold air for rapid start-up.
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.
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.
Also for Use on Mid/High-Pressure Main Lines: The JH7 series employs the same 3-point seating construction found in products for use on main lines. The float is held tightly against the valve opening even under small condensate loads such as in superheated steam lines, so no steam is allowed to escape.

Operation Animations

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.
