BRILEX RSK Explosion Isolation - Non Return Valve |

| In event of a dust explosion in a filter/dust collector, the explosion can travel back via the inlet ductwork to connected machinery or other plant equipment. Should an explosion be allowed to travel back to the plant, the explosion will gain significant speed and will cause catastrophic damage and can be life threatening to personanel in the plant.
Ignition sources such as embers or sparks can be produced by process machinery and then be transported to filters. Filters can produce optimum conditions for dust explosions. The likelihood of an ignition source together with an optimum airborne dust concentration characterises filters / dust collectors as high-risk zones for dust explosions to occur. Correctly designed and certified Explosion Vents in filters will protect their integrity, however an un-isolated filter inlet duct will allow a high-risk hazard to propagate back to the rest of the plant.
Plant managers concerned about occupational Health and Safety as well as plant protection now have a cost effective opportunity for explosion isolation of filters compared to other products such as chemical suppression barriers, diverters and knife gate valves. With a certified BRILEX RSK Isolation Valve it is now possible under certain conditions as layed out in the certification to isolate filters and run the plant economically.
The valve consists of a weighted, hinged, plate inside the main body. In normal operation, the plate is held open by the air flow through the valve. In the event of a dust explosion, the air flow is stalled and the plate will close. The plate will then be driven down hard on the valve seat by the explosion pressure.
The valve must be used in conjunction with a primary protection system on the main vessel such as an explosion vent. The RSK valve is designed for reduced explosion pressures up to 2.2 bar (up to DN400) and 1.4 bar (DN450 onwards). Therefore it should not be used in conjunction with a containment vessel which is capable of withstanding the maximum explosion pressure.
The RSK valves can be used for dust explosionhazards in the ST1 and ST2 classes.The valve must be located horizontally in the inlet duct. The minimum distance between thevessel and the valve is as follows:-
2m - DN160-DN400 or 3m - DN450-DN1000
The RSK valves are constructed from mild steeland painted (RAL3000). Unpainted versions instainless steel 304 are available as an option.
