Product Details
Benefits and Features
All L, LV, and FL series models employ a thermoliquid-filled X-element, which acts as the valve.
- Improved Productivity
- The X-element discharges hot air as well as low-temperature air and cold condensate. This encourages the inflow of steam, thereby reducing start-up times.
- Protects Equipment
- The valve remains open even in the event of a failure due to the 'fail open' construction of the X-element, which means that the equipment can continue operating (though steam loss will occur).
- 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 rust or scale that could obstruct the valve opening.
Application Areas
Suitable for use in a variety of applications.
- Main Applications
- Air conditioning, steam tracers, steam heating equipment, etc.
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.
