    Pressure Relief Valve

    When combustion engines or special gas engines are operating, it is possible that the incompletely combusted fuel mixture gets into the exhaust gas line.

    Possible causes: Not tight closing exhaust valves, an incorrect air / fuel ratio, insufficient fuel supply, an incorrect ignition timing or a too rich fuel mixture.

    If the unburned fuel mixture ignites because of  the glowing hot catalyst, then this would lead to an explosion in the exhaust system. Therefore, the installation of a pressure relief valve (explosion damper) is recommended, especially for large systems. The PRV allows the explosion pressure resulting from the explosion to escape automatically from the system in seconds, thus preventing damage to the exhaust gas line.

    Jeremias pressure relief dampers are made of high-quality 316L stainless steel and can be used up to an exhaust gas temperature of 1112 °F (600 °C). Thanks to the variably adjustable opening pressure, the PRV can be adjusted according to the requirement of respective system.

    PRV

    Pressure Relive Valve

    Relief and monitoring of excessive pressure (backfire or delayed ignition of unburnt fuel) in engine exhaust, heating appliances, and other fuel fired equipment.
    The spring loaded plate keeps seal tight until pressure forces plate open.

    Connection System: 125/150 Lb. flange pattern.

    PRVF

    Flame Retardant Pressure Relive Valve

    Relief and monitoring of excessive pressure (backfire or delayed ignition of unburnt fuel) in engine exhaust, heating appliances, and other fuel fired equipment.
    The spring loaded plate keeps seal tight until pressure forces plate open. A built-in switch alerts maintenance or plant personnel that a
    backfire has occurred.

    Connection System: 125/150 Lb. flange pattern.

    A special material in packed area retards flames from protruding outwards.

    PRVR

    Pressure Relive Valve with Rolled Flange

    Relief and monitoring of excessive pressure (backfire or delayed ignition of unburnt fuel) in engine exhaust, heating appliances, and other fuel fired equipment.
    The spring loaded plate keeps seal tight until pressure forces plate open.

    Connection System: 1/2" rolled flange.
