Desuper Heater and Pressure Reduce Device

Star Controls integrates Emerson Fisher's fluid control technology into an integrated unit to provide users with more convenient and reliable installation, commissioning, and use of DSH units. These quipments are designed specifically in all aspects to solve the common faults and use problems of temperature and pressure reduction devices.

Advantages of the Solution

Better Atomization Effect——High Efficiency

Emerson attemperators are available in a variety of physical configurations and spray types to optimize performance with specified control and installation parameters. The success of a particular desuperheating station may depend on a number of physical, thermal, and geometric factors. Some factors are obvious, while others are more obscure. We analyze these factors through professional software, select the best model, and automatically give the precise installation requirements. To solve the problems of low flow rate water is difficult to atomize, water is accumulated downstream, temperature cannot be controlled etc.
No Leakage Valves——Reliability

Control valve closing leakage is a common problem, mainly because the difference in thermal expansion between the plug and the cage at high temperatures can lead to bonding or excessive loosening, and differential thermal expansion in the body - bonnet- cage - seat system can lead to gasket failure. Star Controls utilizes Fisher regulator technology to eliminate leaks from thermal expansion by selecting similar materials or by appropriate part sizing.
Low Noise, Anti-Cavitation, Low Stress, Vibration Resistance——Safety
- Due to the large temperature and pressure changes, throttling, high speed, impact, phase change and other physical changes occur in a short time, the temperature and pressure reduction device itself is very easy to produce a series of safety problems.
- To reduce noise levels during valve operation, the Fisher noise reduction valve internals are available in three configurations: Whisper Trim™ I, Whisper Trim III and WhisperFlo™ Trim.
- To reduce the effects of cavitation, the Fisher anti-cavitation control valve internals are available in three technologies: Cavitrol™ III valve internals, NotchFlo™ DST and dirtier valve internals (DST).
- To minimize stress and overcome the effects of vibration, Emerson innovation center analyzes complex geometries, locates stress concentrations, and makes design modifications to significantly improve fatigue life. Through structural design and reinforcement of local structure, vibration robustness is improved.
Precise Driving——Stability

FIELDVUE™ digital Valve controllers use special control and tuning algorithms for stable, high-performance control.
Overall Design is Reasonable——Flexibility

According to the user's situation, through flexible configuration of various components, overall design and manufacturing, Star Controls make the entire device structure more compact, convenient installation and commissioning, easy operation, reliable performance, and reduce the overall cost.
