NOVEX Filter Isolation Valve DN71-DN100
Part No. DN71-DN100
The Novex valve is an explosion-proof flap valve certified as a protection system according to Directive 94/9/EC and according to EN16447: 2014. It is completely autonomous and must be installed on a horizontal piping, at a certain distance from the protected volume.
Features
- Available from DN71 to DN1000.
- Automatic locking of the valve in the closed position in case of explosion.
- Painted carbon steel (MS) or stainless steel (SS) 304 finish
- Pred max 1 or 2 bar, depending on DN and type of dust
- Organic or metal dust St3 Kst max 440 bar.m / s
Product Details
When stopped and in normal operation, the valve blade is held open by two magnets.
If during operation of the process, an explosion occurs behind the valve, the airflow is immediately reversed by the rise in pressure and the rest of the installation upstream of the valve is effectively isolated from the propagation of the explosion.
The blade remains locked in the closed position. A hinged inspection hatch at the top of the valve allows easy access for critical point checks such as dust accumulation or seal condition.
