Deluge Ultra High Flow Performance Relief Valves

27 January 2009

Brownell has introduced a range of Ultra High Flow Performance Relief Valves with standard sizes of 25 mm to 200 mm.

An unusual operating characteristic for this pressure relief valve is proportional decrease in back pressure after the relief valve has opened at the set pressure and increased flow is required.

This allows a significantly high increase in gas flow when compared to similar size relief valves. With high reaction speeds of less than 0.2 seconds these pressure relief valve are suitable for over pressures 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 specification for pressure settings is from 0.5 to 5 psi for opening pressures and vacuum relief. The pressure relief valve can operate in aggressive environments including corrosive chemicals, driving rain, low and high temperatures. A weather and impact shield provides further mechanical and physical protection.

Additional features options also include debris filter, EMC screening and manual relief override.
