Steam Trap/Radiator Product
TSD - 42F
*High corrosion resistance due to main parts made of stainless steel. *Operate under 425 degrees C temp. and 4.2 MPa pressure. *The adoption of a bimetal solves air locking, and ensures a smooth discharge of cold condensate and air at the start of operation. *Can be installed vertically or horizontally as desired. *Built-in strainer *\\\"Insulation cover\\\" avoiding freequent on-off is available. |
