Explosion Isolation & Diversion

Protect connected vessels and pipelines from secondary explosions

Craig Equipment Co. uses Explosion Isolation and diversion valves to protect connected pipelines and vessels from catastrophic secondary explosions that propagate from the primary event.

Boss Explosion Isolation & Diversion Solutions

Explosion isolation valves should be placed on the protected vessels’ inlet, outlet, hopper discharge, 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.  

Proper Testing of Explosion Isolation Valves

Our Commitment to Industrial Safety

Craig Equipment Co. is committed to helping you meet and exceed today’s strict NFPA regulatory guidelines governing American industry. We provide a full range of fire and explosion mitigation solutions to address potential hazards in the industrial filtration and process industries. Craig Equipment brings decades of experience to the design, engineering, and installation of containment solutions for multi-application industrial dust collection, bulk handling, and process systems. We believe BOSS Products has developed a family of SAFETY SMART solutions to work as individual components or as a seamless plantwide solution to meet the needs of industrial safety in the USA.

VIGILEX Explosion Isolation Valve EV-VF VigiFlap

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 airflow or a 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 explosion containment.

Float Valve EM-FV

EM-FV Float Valves are 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. Single and double-acting models are available.

A regular inspection and maintenance schedule are required to ensure that dust deposits that could interfere with the valve’s function are not accumulating.

Explosion Diverter EV-VDIV

The Explosion Diverter EV-VDIV 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.
