Steam Traps

Automatic valves for the purpose of discharging condensate without venting steam.
Operating Pressure Range: 0 - 260 barg
Operating Temperature Range: 0 - 550 °C
Product Selection by Application
Subcategories
Mechanical Steam Traps
Mechanical steam traps utilize buoyancy to open and close the valve.Also known as 'Float Traps' or 'Bucket Traps'.
Thermodynamic Steam Traps
Steam traps that utilize the difference in the thermodynamic properties of condensate and steam.Also known as 'Disc Traps'
Thermostatic Steam Traps
These traps utilize the difference in the temperatures of steam and condensate.Also known as 'Temperature Control Traps' or 'Balanced Pressure Traps.'
Benefits and Features
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.
Application Areas
Below are some common applications and the steam trap types that are often used for each application:
- Steam Transport Lines (Steam Main Lines)
- – Free Float® for main lines
- – Disc type
- Steam Heating Equipment
- – Free Float®
- – Thermostatic
- – High-capacity Free Float®
- Tracers, Freeze Protection, Room Heating
- – Thermostatic
- – Free Float®
- – Temperature control traps, radiator traps
The different types of traps can also be used in numerous other types of applications in addition to those mentioned above. Contact your TLV sales representative for details.
Product Selection by Application
This guide shows the most suitable TLV steam traps for an array of applications.
Start by selecting an application from the drop-down menu at the top, then search for your desired operation principle, pressure category, and other special features to find the right steam trap.

*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.
