Nederman CARZ FL200 Explosion isolation flap valve

• Used in pneumatic conveying systems to prevent explosion propagation.
• Installed in dust extraction lines handling combustible materials.
• Integrated into filtration systems for fine particulate matter.
• Deployed in material handling processes where dust explosions are a risk.

Typical connection diameter

For this model (FL200), it typically refers to a 200mm nominal bore for ducting.

Explosion pressure resistance

Units of this type are commonly designed to withstand explosion pressures up to 15 bar.

Activation mechanism

These are passive devices, activating automatically upon an explosion pressure wave.

Material construction

Typically constructed from robust steel, suitable for industrial environments.

Installation orientation

Commonly installed horizontally in ducting, requiring specific upstream/downstream clearances.

Certifications

Units of this class are typically ATEX certified for use in potentially explosive atmospheres.

Gas supply and monitoring systems are regarded as critical infrastructure in laboratory and pharmaceutical settings. Buyers typically prioritise reliability, accuracy of monitoring, and compliance with safety standards when purchasing used equipment. Key considerations include maintenance history, calibration records, and compatibility with existing facility systems. These systems generally offer good value when sourced from well-maintained stock, with durability and consistent performance being notable strengths. Proper verification of function and documentation remains essential before purchase.
