Explosion Isolation & Diversion
Prevent secondary explosions by isolating or diverting the primary event.
Explosion isolation valves should be placed on the inlet, outlet and hopper discharge of protected vessels and interconnecting pipelines to prevent deflagration propagation. Isolation valves are available for a variety of orientations and dust types. Diversion valves are also available with multiple options. Our engineers will work with you to determine the proper valves for your facility and application.

VigiFLAP Explosion Isolation Valve
VigiFLAP Clapet Anti-Retour
EV-VF VigiFlap Datasheet
EV-VF VigiFlap Explosion Isolation Valve
The VigiFlap is an explosion isolation valve designed to prevent propagation of overpressure or flame front caused by an explosion downstream in vessels such as dust collectors, cyclones, and filters.
The valve is held open either by air flow or proprietary locking mechanism. As a result, the VigiFlap valve can be used as an explosion isolation device for both the inlet and oulet of a vessel.
The VigiFlap Explosion Isolation Valve complies with NFPA guidelines and is an ATEX Certified device for the containment of explosion.
No Return Valve Datasheet
No Return Valve Combo/Metal
The installation of an Explosion Isolation device on all suction side ducts that transport material with a Kst value above zero is an NFPA Requirement.
Installing a No Return Valve Combo/Metal will protect workers and facilities from the damaging effect of a baghouse or filter explosion.
The No Return Valve Combo/Metal is designed for use with all EcoMAXX® High Speed Abort Gates, Fire Break Shutters, Raptor Spark Detection & Extinguishing/Suppression Systems, and Energy Management Systems.
Float Valve EM-FV Datasheet
Float Valve EM-FV
The Float Valve EM-FV is designed as an explosion isolation device in air streams with low to low moderate dust concentrations. The maximum allowed recommended particle size is approximately 500 microns. A regular inspection and maintenance schedule is required to ensure that dust deposits that could interfere with the valve’s function are not accumulating.
Explosion Diverter EV-VDIV Datasheet
Explosion Diverter EV-VDIV
The EV-VDIV Diverter Valve with integral explosion panel is the ideal addition to any exterior process flow duct system where there is potential for hazardous explosive overpressure or multiple explosive events. This device helps reduce the potential for system damage caused by high overpressure and rapid flame front expansion.
Rotary Valves
Rotary valves for industrial manufacturing are often used to isolate devices when an explosive event occurs in a vessel by isolating that vessel and stopping the flames from propagating and causing secondary events to occur.
