Description

Sizes and pipe connections

", 1⁄2" LC, 1⁄2" and 3⁄4" butt weld Schedule 40.

Pressure / temperature limits

The TD3-3 is a medium pressure thermodynamic steam trap fitted

between unions for ease of replacement. Tail pieces are prepared

for butt weld ends.

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 to " BSP or NPT.

Standards

The product fully complies with the requirements of the European

Pressure Equipment Directive 97/23/EC.

Certification

This product is available with certification to EN 10204 3.1.
