Details
| TB7N | Steam main lines and tracing lines, low and medium pressure applications |
| TB9N | Steam main lines, tracing lines, low and medium pressure applications |
| TB51, TB52 | Steam tracing lines, low pressure applications |
| TB81, TB82 | High pressure steam main lines, high pressure applications |
Features
| All traps are equipped with the patented valve mechanism SCCV® -System | ||
| The SCCV® System ensures a superior closing performance in the center of the port, greatly reduced wear of the internal parts and extended life of the trap | ||
| Highly efficient in energy conservation – eliminates virtually 100% of steam loss | ||
| Continuous discharge of the condensate according to the adjusted temperature – not influenced by inlet pressure changes | ||
| Inline repairable – easy and quick replacement of the bimetal unit and the seat | ||
| Readjustment possible while the trap is in operation (for low pressure applications) | ||
| All traps equipped with integral strainer |
Operation
| 1) On start-up, the bimetal discs are all flat and the valve shaft is up with the valve fully open. Virtually all cold condensate and air are discharged. |
| 2) As the temperature of the condensate increases, the bimetal discs begin to curve gradually and force the valve shaft and the valve holder to move down. Most of the condensate is still discharged quickly, since the valve and the holes in the fixed guide on the valve seat are still fully open. |
| 3) When condensate with higher temperature (near to set temperature) flows in, the bimetal discs are curved even more and at the same time the valve shaft moves down and the valve holder closes the holes in the guide partially. The amount of condensate being discharged is reduced quickly. This prolongs the time that the hot condensate stays near the bimetal discs and the heat of the condensate is transferred to the bimetals much more effectively. |
| 4) In case of very low condensate flow, the holes in the guide are closed completely by the valve holder and the valve will close precisely in the center of the seat. Normally, the trap is filled with hot condensate and the operation will rest in the state shown in figure 3. Condensate will be discharged continuously at a stable temperature (very close to the set temperature). |
