Explosion isolation system Q-Flap RX™

The Q-Flap RX™ is also perfectly suited, for the aspiration lines of filtering dust collectors, and for the suction intake lines of mills. The nominal pipe sizes up to DN 400 are primarily used for decentralised extraction systems in the pharmaceutical and chemical industries, whereas nominal pipe sizes between DN 450 and DN 710 are also used for centralised dust extractors in the grain and food industry. Nominal pipe sizes from DN 800 to DN 1000 are used in the wood and heavy industry. Advantages • Quick maintenance without the need for a complete dismantling of the device, simply by completely opening the inspection flap on pipe sizes up to DN 710. • Optionally: longer maintenance intervals by integrating a supervision function. • No boundary’s: Q-Flap RX™ available up to DN1000. More sizes available on request. Mechanism When the system is shut down, the valve blade rests in an inclined position. During normal operation, the explosion isolation flap valve is kept open by the air flow of the system. In the event of an explosion, the valve blade is closed by the pressure wave of the explosion.
