Fike Corp. announces the ValvEx passive isolation explosion protection solution for dust aspiration and dilute-phase pneumatic conveying systems.

The ValvEx passive explosion isolation valve is designed to prevent flame and pressure propagation through interconnected pipes, ducts or conveying lines to additional process equipment or operating locations.

"Thanks to Fike's dust explosion propagation research campaign, Fike is able to define the dominant explosion parameters that affect flame and pressure propagation in a vented vessel-pipeline system. A correlation between venting parameters and valve performance was found, and Fike has identified conditions under which valves do fail," explained Bob Korn, Fike's director of sales and marketing.
 
"An explosion propagating through a vented pneumatic conveyance system is a fairly complicated fluid dynamic process. Through Fike's extensive flame propagation research, this knowledge has enabled us to design a passive explosion isolation valve that prevents unwarranted failure," said Stephen Clegg, Fike's explosion protection product manager.
