Spirax Sarco Td42 Thermodynamic Disc Steam Trap - China

price: contact company for price

GATD42 thermodynamic steam trap.

Pressure Rating: 1.6- 6.4Mpa.

Specification: DN15- 50.

Material: cast steel.

Standard screwed: NPT.

Structural Characteristics.

1. Assembled with steam or air heat preservation mechanism and unaffected by the environmental humidity; with operation frequency decreased, its service life prolonged.

2. Provided with filter screen and drainage valve .

3. The valve runs flexibly and reliably with large displacement.

Working Principle.

By taking advantage of thermodynamics characteristics, secondary evaporation will arise when the condensate water is discharged to the lower pressure zone and meanwhile when the viscosity and density of steam differ, the drain valve will open of close.

Main Function.

The valve is applicable in the steam pipeline and equipment to avoid steam leakage and eliminate steam leakage in order to conserve energy and keep from water hammer and other faults.
