Spirax Sarco TD42 Thermodynamic Disc Steam Trap
Model: TD42
Category: Automatic/Industrial Machines & Equipments / Industrial Machines / Valves
Specifications
TD42 Thermodynamic Steam trap
TD42 Steam Trap is a kind of thermodynamic steam trap which is mainly used for the environment with low condensate backpressure and low capacity requirement, similar to Spirax Sarco Design
TD42 thermodynamic steam trap
Pressure Rating: 1.6- 6.4Mpa
Specification: DN15-50
Material: cast steel
Standard screwed: NPT
TD42 Thermodynamic Steam Trap Structural characteristic
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.
TD42 Thermodynamic Steam Working principle:
By taking advantage of themodynamics 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.
TD42 Thermodynamic Steam Trap 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.

Thermodynamic steam traps operate on the basis of the Bernoulli principle, depending on the relationship between the velocity and the pressure exerted by the condensate and steam inside the steam trap. They have only one moving part - the disc.
Due to their compact design and cost effectiveness thermodynamic steam traps are widely used in applications where the condensate must be removed immediately from steam lines and steam equipment. They discharge the condensate near the saturation temperature.
The traps may operate up to a back pressure of 80% of the inlet pressure, but for smooth operation it is recommended that the back pressure does not exceed 50% of the inlet pressure. Thermodynamic steam traps discharge the condensate intermittently.
All steam traps are equipped with a hardened stainless steel disc and seat. After the lapping process all disc surfaces are controlled individually before releasing them for use in steam traps. These features and very high and severe quality standards for the whole production process give MIYAWAKI`s thermodynamic steam traps a long and reliable service life.
