Description

The TD42 is a maintainable thermodynamic steam trap.

The TD42LC is specifically designed 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 Equipment Directive 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.

", 1⁄2" LC - Low Capacity, 1⁄2" and 3⁄4" screwed BSP or NPT.

Optional extras

Insulating cover: to prevent the trap being unduly influenced

by excessive heat loss such 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

and plugged " BSP or NPT.
