Q-Flap RX™

Effectively isolated.

Isolating of raw gas lines to filters + separators.

In the event of an explosion, the Q-Flap RX™ explosion isolation flap valve effectively isolates plant components in almost all industrial sectors. In order to meet the highly diverse requirements for the individual industries, the Q-Flap RX™ product range offers three different design versions. The nominal pipe sizes up to DN 710 feature an inspection flap, and the larger nominal pipe sizes have a modular design. This ensures that a maintenance and servicing of any pipe size can be carried out easily.

Application

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.

Spare parts set

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.
