The Interceptor-FV explosion isolation flap valve is a passive solution that automatically closes during a deflagration event, effectively stopping flame and pressure propagation in pipelines.

The flap valve goes above and beyond regulatory requirements and meets EN 16447 approval and complies with NFPA 69. The flap valve includes an NFPA-required integrated dust accumulation sensor that warns the operator when valve requires cleaning and an access door that facilitates dust removal, maintenance, and inspection.

The flap valve suits either pressure or vacuum systems and is approved for handling metal dusts and ST 2 materials. Its mechanically held flap only closes during an event, allowing the valve to be installed vertically, horizontally, or at an angle for application flexibility. It fits pipeline sizes up to 32 in. in diam, with approval for metal dust applications in pipelines up to 16 in. in diam.
