Benefits and Features

Improved Efficiency of Heating Equipment

The float (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 (models with '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 (models with 'B') functions as an air vent, discharging initial cold air for rapid start up.

Long Service Life, Excellent Durability

The high precision spherical float rotates, allowing its entire surface to function as valve sealing surfaces and thus ensuring long service life.

Protects Equipment

The X-element is designed to fail open, so the valve remains open even in the event of failure (fail open design).

Also for Use on Mid to 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.

Application Areas

Especially suitable for steam processes.

Main Applications

Heat exchangers, reactor kettles, vulcanizing pans, jacketed kettles, roller heat exchangers, cylinder dryers, steam main lines (some models), etc.
