Benefits and Features
Space-saving Design
The integral bypass valve eliminates the need for a separate bypass line, thereby saving space at the trap installation.
Reduced Pipeline Costs
Installation costs are reduced, as neither a bypass valve nor bypass piping are required.
Energy Conservation
Utilizes the TLV Free Float®. The combination of the valve opening being under a continuous water-seal and the 3-point float seating prevents steam leakage.
Long Service Life
The spherical Free Float® rotates, allowing any point on its surface to act as the valve seal and thus ensuring long service life.
Inline Trap Maintenance
Maintenance is possible without removing the trap from the piping. For disassembly and cleaning, simply remove the four bolts securing the cover of the trap.
Application Areas
- Steam main lines, steam headers, presses, tracers, etc.
