Double Flap Airlock Valve Technology Critical to Efficient Melt Shop Baghouse Operation
By Kevin Guay, Senior Sales Engineer Research & Development

If you operate a steel mini mill, you know how critical it is to have a melt shop baghouse that operates efficiently and without interruption. After all, when your melt shop baghouse is down, you have to cease or curtail your operations. And that costs you money. For steel mills with recurring unplanned baghouse downtime, the root cause of the problem is often the use of rotary discharge valves that bridge, jam, and plug.

Although rotary discharge valves are in widespread use in melt shop baghouses, there are fundamental shortcomings in the design that make them ill-suited for the unique demands of the baghouse environment. By contrast, the design of double flap valves has proven to be inherently better suited for the steel mill baghouse environment.

In this whitepaper, we explain the types of baghouse discharge valve-related problems that can disrupt melt shop operations. We also provide a comparison of the rotary valve and double flap valve designs and illustrate how double flap valve technology can eliminate costly baghouse efficiency and reliability problems to increase your throughput, reduce costs, and reduce the risk of environmental compliance issues.
