TD42 Thermodynamic Steam Trap
3 2
Description
The TD42 is a maintainable thermodynamic steam trap. The TD42LC is specificallydesigned for relatively small condensate load and is, therefore, ideal for mains drainage applications. Standards This product fully complies with the requirements of the European Pressure EquipmentDirective 97 / 23 / EC. Certification This product is available with a manufacturer’s Typical Test Report. Note: All certification / inspection requirements must be stated at the time of order placement.

/ ", ½" LC - Low Capacity, ½" and ¾" screwed BSP or NPT.
Optional extras
Insulating cover: to prevent the trap being unduly influenced by excessive heat losssuch as when subjected to low outside temperatures, wind, rain, etc. Integral blowdown valve: a BDV1 or BDV2 can be fitted to the strainer cap, alternatively the strainer cap can be drilled, tapped andplugged " BSP or NPT.
