Who hasn’t been woken at dawn by a noisy trash collection truck? Sometimes it seems the rasping engine and whining hydraulics were designed specifically to rouse entire streets, but that’s changing. Growing numbers of trash collectors, like Waste Pro, are converting their fleets to compressed natural gas (CNG.) CNG offers several benefits, including quieter operation, but also raises some issues relating the refueling.
Any liquid or gas leak is a problem, but especially so if it’s a corrosive, toxic or flammable fluid. Incorporating an excess flow valve, or EFV, into pipework improves safety by sealing off the flow should a pipe break or be disconnected.
When hurricanes, wildfires or simple electrical system overloads cut the power to cell phone towers, diesel backup generators typically are the only way to keep the calls coming. But diesel requires maintenance and man-hours. An alternative, hydrogen, requires much less maintenance and man-hours to maintain.
Public transportation across the country has been using CNG for decades, with about 12-15% of public transit buses in the U.S. currently running on natural gas (either CNG or LNG – liquefied natural gas). That number is growing, with nearly one in five buses on order today slated to run on natural gas. States with the highest consumption of natural gas for transportation are California, New York, Texas, Georgia, Massachusetts and Washington, D.C.
We know many distributors, engineers and customers have the knowledge needed to select the right valve for their application. But, if you’ve got questions and want to save time, we recommend you download and read our new white paper, “A Guide to Selecting an Excess Flow Valve,” to make sure you’ve completed the checklist.
