A pressure surge or wave caused when a fluid is forced to stop or change direction abruptly is called water hammer. Often it is caused by a valve closing. The pressure wave can cause major problems, including pipe rupture. Using devices such as pulsation dampeners can reduce the effects. If you are having issues with water hammer in your Equilibar fluid control valve, please visit our chatter support page . For a detailed explanation of how to analyze water hammer issues, see this video from Mike Crowley with Fluid Mechanics in the UK.

When people open their kitchen cabinet, they probably don’t think about how the icing was drizzled on their favorite cookies or how a bottle of apple juice was filled. They most likely assume that their cans of vegetables will be good to eat for months and their bags of snacks will stay fresh. People don’t Read More
