03.09.2018 Explosion isolation flap valves

The Ratingen, Germany, arm of IEP Technologies – part of the HOERBIGER Group – has introduced the IFV and IFV-M isolation flap valves. These self-actuating devices are said to be cost effective, easy to install, and reliable. Used in a wide range of industries where dust hazards may exist, isolation flap valves are designed to provide explosion protection between process vessels such as dust collectors and cyclones.


Explosion isolation valves are typically required where two or more process vessels are linked by ductwork and an explosion hazard exists. An isolation flap valve installed in the duct is closed rapidly by the pressure wave from the downstream explosion ahead of the flame front arrival. By stopping the flame from reaching the upstream vessel, it prevents the flame and explosion pressure from reaching attached vessels and creating a secondary, and often more devastating explosion. The IFV flap valve is compliant with the ATEX Directive and certified by a third party as a dust explosion protection system. The IFV-M model adds integrated monitoring of the flap position and dust accumulation in the valve body, meeting the requirements of the OSHA Combustible Dust Directive, NFPA 654, and NFPA 69. www.hoerbiger.com
