Why Do DFT® Axial Flow Check Valves Inherently Reduce Water Hammer?

Posted by Jeff Kane on

Hydraulic shock—more commonly known as “water hammer”—occurs when the flow within a pipe is suddenly forced to change direction, which creates a pressure wave that can be characterized by a loud knocking or banging sound. In piping and process systems, water hammer often happens upon closing a valve to stop or redirect flow. It’s important… Read More
