Product Details
Benefits and Features
- From Low Pressures to Super-high Pressures (260 barg)
- Only at TLV has a line of thermodyne (disc) steam traps been developed that offers traps to cover the complete range of pressures used in the industrial world.
- Energy Conservation
- Disc steam trap operation may suffer if the trap is exposed to cold air and rain, so to prevent wasteful leakage of steam TLV has developed an air-jacketed pressure chamber model, and for even greater insulation, a steam-jacketed pressure chamber model. The high-precision machined disc valve and valve seat offer excellent sealing properties, preventing wasteful discharge of steam.
- Improved Productivity (Bimetal Type Automatic Air Venting Feature)
- Productivity is impaired if the large amounts of cold condensate and air inside the system are not discharged as soon as the equipment is started up. With the exception of models P21S, HR150A and HR260A, all models have an integral bimetal type automatic air venting feature. The valve is fully open when temperatures are low, allowing for the rapid discharge of cold condensate and air.
- Easy Maintenance
- With the exception of models P21S and FP32, the valve and valve seat of all models are a single, modular unit, allowing for easy and economical maintenance when replacement is necessary due to wear, etc. The entire trap on model FP32 is inline replaceable.
Application Areas
Steam main lines, heat exchangers, jacketed kettles, room heating, tracers, coils, etc.

*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.
