“Trouble Less Valve” – This is what the name TLV stands for.
TLV was founded in 1950 with the goal of creating
the world’s No. 1 steam trap.
Witnessing the problems and challenges faced by
plants, our pursuit evolved into a determination
to bring plants peace of mind.
This inspired a change – what customers need are
solutions, not just products.
Drawing on our experience, TLV will continue to
provide solutions and value to plants,
striving to become the world’s No. 1 steam specialist.

A3N
A3NSteam-heated,
condensate-cooled
disc-type steam trapOur first milestoneWe developed the A3 after seven years of dedicated research. Designed to alleviate the high frequency of steam trap failure, it was over ten times more durable than existing products. Despite being three times more expensive than competitors, it earned an outstanding reputation in the market. Its legacy is inherited by the improved A3N, a bestseller even today. -
Free Float®Free Float®Meeting energy-saving needsThe Free Float® is a symbol of TLV’s technical expertise. Our steam traps incorporating this technology have very low steam loss and long service life. Today, our Free Float® technology is used widely in a broad range of products. -
VACUUMIZER®VACUUMIZER®Vacuum steam heating systemExpanding the possibilities of steamWe have also pioneered the development of system solutions – devices that incorporate multiple TLV products to perform specialized, controllable functions. Our vacuum steam-heating system VACUUMIZER®, for example, allows you to harness steam’s heating properties even below 100 °C.

Manufacturing “TLV Quality”
Customers First
Providing the best possible solutions
Through developing products and studying the steam-using processes in our customers’ plants, we came to realize that there are many problems in the steam system that cannot be solved by just providing products.
To proactively contribute to safe and reliable plant operations, we created the CES (Consulting・Engineering・Services) philosophy and team.
The aim of CES is to offer the best possible solutions to problems that steam-using plants face, increasing energy efficiency, protecting the environment, and improving product quality and productivity.

Optimizing your steam system
The organizational benefits of utilizing steam to its full potential and treating the steam system as an asset are significant.
SSOP® (Steam System Optimization Program) improves the safety and reliability of your plant.
In SSOP® we create clear visualizations of even complex steam systems and implement mechanisms that help keep plants in their optimal state.

Steam System Optimization Program
Continuously optimizing steam systems through visualization
Steam System Optimization Program
-
Condition MonitoringWe use diagnostic devices to monitor and visualize the entire steam system in real time. Visualization and analysis of the operating condition of all steam-using equipment reveals opportunities for further improvement.
-
Timely OptimizationWe establish a system that detects early signs of failure, enabling fast and accurate maintenance to be performed before trouble occurs. This supports safe and reliable plant operation, reduces risk and saves energy.
Steam is an asset
Creating the future of steam plants
There is more to SSOP® than total plant surveys and state-of-the-art monitoring systems.
We also uncover risks early and take preventative measures, mitigating the negative impact of system failure.
By uncovering risks early and taking preventative measures, we aim to prevent the negative impact of appliance or system failure.
A wide range of steam facilities around the world are reaping the rewards of SSOP® for their critical tracing applications, turbines, reboilers and other assets.
