The Deluge pressure relief valve is a new design Brownell Ltd has developed, for over pressure and vacuum relief applications.
The range has standard sizes of 25-200mm. These valves have an unusual operating characteristic. After fully opening there is a proportional decrease in back pressure. This allows significantly higher increases in gas flow when compared to similar size relief valves.
These valves have reaction speeds of less than 0.2 seconds this product is suitable for various applications, such as over pressure in pipelines, pressure vessels, storage vessels, equipment containers and safety relief applications. The deluge relief valves are fully automatic and reset after opening, even when maximum flow performance has been achieved.
The standard range of pressure settings is from 0.5 to 5 psi for pressure and vacuum relief. These products can operate in aggressive environments, including corrosive chemicals, driving rain, and low & high temperatures. A weather and impact shield provides further mechanical and physical protection. Additional product options also include debris filter, EMC screening and a manual relief override.
