IBEDA Germany has New Helium-Vacuum Leak Testing Equipment that has increased production capacity by 50%, thus allowing for further investment in automated manufacturing of gas non-return valves (check valves), gas safety devices and quick action couplings. With the new Helium-Vacuum leak testing equipment, production of IBEDA finished product has increased by 50%. This will enable increased fulfillment for the rising demands of high quality safety devices and quick couplers, while keeping reliable delivery and ensuring availability of 100% tested high quality products. Every IBEDA arrestor is submitted to a flashback test. With the new test equipment, each unit is additionally tested for slow reverse flow of gas (≤ 50cm³/h), for external gas tightness (≤ 8cm³/h), for a proper reset function (for products with pressure sensitive cut-off valve) and for leaks once this valve is released (≤
Using a flashback arrestor is the best way to stop flashbacks from occurring. They have the essential element that stops flashbacks — a flame barrier. A flame barrier stops the rapid flame propagation through hoses, regulators and torches. Without this protection, check valves cannot stop a flashback. Want to see how flashback arrestors work? Check out our demo below!
Flashback Arrestors Designed to stop a flashback AND prevent reverse flow Flashback Arrestors have a flame barrier which stops a rapid flame propagation through hoses, regulators and torches. Flashback Arrestors also include an internal Check Valve which is protected by the flame barrier. SuperFlash Flashback Arrestors can come with a thermal shut off that can stop hose burnback and repeated flashbacks. SuperFlash Flashback Arrestors are U/L approved and OSHA compliant! SuperFlash Flashback Arrestors will stop a flashback even if the internal check fails or leaks. Check Valves Check Valves only prevent the reverse flow of gases, and CANNOT stop a flashback. Check Valves do NOT have a flame barrier Check Valves do NOT contain an inlet filter, which keeps out dust and debris. Check Valves need to be checked at least annually, or more often in abusive or heavy duty applications. Most people don't take the time to inspect them! If a Check Valve fails, the reverse flow
