SO – Steam Traps

Steam Traps

A steam trap is a kind of automatic valve that discharges condensate generated during processes and in steam transport lines while preventing any steam from escaping (‘trapping’ the steam). Steam traps can be divided into three general categories based on their operation mechanism: mechanical, thermodynamic, and thermostatic. TLV manufactures all three of these categories.

Our extensive product line-up makes it possible to select the optimal product to suit your objective or application. Each trap offers the highest level of energy conservation in its class. Much consideration is given to the aspect of maintenance, as evidenced by designs that include the unitization of parts, interchangeable parts, and utilization of re-useable PTFE gaskets.

Mechanical Free float trap
The operation principle of mechanical traps takes advantage of the difference between the specific gravities of condensate and steam.
Free Float® steam traps, a TLV invention, are our flagship series of mechanical steam traps. Free Float® steam traps offer the following features:
• The spherical float provides an infinite number of contact surfaces with the valve seat, ensuring long service life.
• Air venting feature for improved equipment productivity.
• Compact design with no levers or hinges.
• Large tolerance for backpressure allows for problem-free operation even where condensate is recovered.

The operation principle for these traps utilizes the difference in the thermodynamic properties of condensate and steam.

Disc-type traps and impulse-type traps are both examples of steam traps belonging to this classification. TLV’s thermodynamic steam traps are all disc-type traps, which allow less steam leakage and have fewer problems with scale and build-up of dirt.

Suitable for a variety of applications, such a steam main lines, tracers, steam heating equipment

Balanced pressure Thermostatic steam traps
The operation principle for thermostatic steam traps utilizes the temperature difference between steam and condensate.

TLV traps offer three types of temperature-sensing materials to detect differences in temperature:
• Thermoliquid
• Bimetal
• Thermowax

Suitable for use on air conditioning, room heating, steam tracers, etc. Models suitable for use with steam heating equipment are also available (thermostatic steam trap L-series).

Radiator Traps
Thermowax is employed as the temperature-sensing medium in these steam traps.

Long Service Life
• Any rust or scale entering the trap from the piping is discharged together with the condensate through the large valve opening, greatly reducing the chance of a build-up of scale that would obstruct the valve opening.
• The spherical stainless steel ball resists wear on the sealing surfaces and exhibits superior durability.

Easy Maintenance
• The trap can also be disassembled and parts can be replaced while still installed in the piping.

Application Areas
• Radiators for room heating, convectors, baseboard heaters, unit heaters, etc.

Bimetallic Steam Traps
Bimetal element is used for temperature sensing, and the user is able to set the condensate discharge temperature.

Energy Conservation
• Discharges condensate at the desired temperature below the saturation temperature of steam.
• The sensible heat in the condensate is also used, making it possible to minimize the amount of steam used.

Long Service Life
• The overexpansion mechanism protects the bimetal element from being subjected to excessive force, thereby minimizing deterioration of the bimetal.

Easy Maintenance
• Condensate discharge temperature is adjustable without disconnecting the trap from the piping.
• The trap can also be disassembled and reassembled while still installed in the piping.

Built-in Scale Removal Function (LEX3N-TZ, FX1).
• Clogs in the valve seat can be eliminated without disassembling the trap.
