Product details

High Steam Low Water (HSLW) Safety Valve is a specialized type of safety valve used in steam boiler systems to protect against the dangerous condition of high steam pressure combined with low water level.



Flange connection acc. to ANSI B16.5



Operating temperature: stainless steel material -60 °C to +300 °C, cast steel material



 






 
features


 



1.Sensing mechanisms to monitor steam pressure and water level simultaneously.

2.Integration with boiler control systems or alarms to provide timely warnings and initiate corrective actions.

3.Robust construction and materials to withstand the harsh conditions of boiler operation.



 





Possible Cause Of The Fault



 



1.System Overpressure or Underpressure: If the valve fails to adequately reduce the pressure or if the system experiences overpressure, potential causes include:



Inadequate sizing or selection of the valve for the application.

Changes in system conditions or operating parameters beyond the valve's design limits.

Failure of upstream pressure regulation devices or control valves.



 



2.Corrosion or Erosion: Corrosion or erosion of valve components can occur due to:



Exposure to corrosive fluids or environments.

Inadequate material selection for the valve construction.

Improper maintenance practices or neglect.
